Here I am sat in the rain awaiting greenflag Mahoosive misfires , no power at all, can't get above 20mph ..... 0300, 0300. 0303. 0305. Coil pack ? :(
-
Codes match 1-3-5 bank, could well be :-\
-
On petrol as well?
-
Yup, first thing I checked. Light misfire at about 1200 rpm no load, revs freely to red line. Put any load on and mahoosive misfire throughout range. EML initially flashes then comes on steady. Codes as above :(
-
pulled out the cp yet? oily?
-
Now home, cold wet and miserable .. its persisting down :( Had no tools to pull the CP ... that will be done first thing in the morning .... off to find the "how to" on CP removal - after I've had a coffee to warm up !!
No sign of any oil leakage from the cam covers, and no sign of water dripping off the scuttle - as best I could see before it got too dark
-
1/3/5 dead easy. Fuel lines off, then you have full access.
-
To remove a CP,
unplug loom
undo 2 bolts
using 2 bolts from plenum, screw these into the brass inserts in the bolt holes in cp, about 3 or 4 turns
use these bolts to help lift cp out.

IIRC you just need a couple of M8/M10 :-\ bolts to screw into the brass inserts ........ and use them to pull it out :y

Reckon you may need to pull plenum off to get to fuel lines - can't remember :-[
I can get to mine (1/3/5) without touching LPG, my 2/4/6, I have to undo one bank of injectors. But obviously all LPG installs vary
-
Check the B1 Long term trims before clearing any codes - wonder if a lamda has caused it to go way off

Not a help here, but its something to consider on the V6 install. On the 2.2, injectors only get in the way of a cam cover change

Limited room means there is no perfect positioning. I actually like the Bullet's positioning, but it does foul the deadening on the bonnet.
-
Position of my injectors probably gets in the way at a guess, but we'll find out in the morning :)

0%, or there abouts. You need to read these **BEFORE** you clear any codes.

Tunnie, when the time comes, Doz borrowed my templates for making suitable brackets for the lpg injectors.
One side uses the cable tray bolts, tother uses the bolts that hold the fuel rail to the inlet manifold, keeping the plenum clear :y designed for the injectors in your first link in tother thread, but plain enough to be adaptable :y

B1 - 0.06%
B2 - 0.04%
But I now remember resetting the codes at the roadside when it first started .. :( before calling greenflag. Car has been started about 5 times and driven less than 50 yards in total since then.
Codes this morning after a reset and within 3 minutes - 0300, 0305 EML on
Plug wells absolutely bone dry - no oil or water

Sorry for the poor quality of the pics .. I'll find a real camera and try harder !!
Plugs have done 54000.
Is there any way of checking the CP other than replacement ?? or am I driving to swidnod and flashing by ABS card at the stealers ?? :)
-
1/3/5 dead easy. Fuel lines off, then you have full access.
Can be done without disturbing fuel lines on 3.2 . ;)

looking at it .... possibly .. but as I had to take off the LPG bits two big nuts for the fuel lines was not a big extra ... :)

When I replaced the 246 CP a few weeks ago I changed the plugs in there as well. Decided to do the plugs on the 135 whilst spanners out. Can take the CP out easily without depressurising the petrol line. Pretty much a 10 min job to change the 3 plugs that side, unlike the 246. Your LPG would make a difference though.
Any rust or crud buildup where the three plug stalks meet with the base? Cracks/tracking evident where the pack might be breaking down?

Now you've asked, and I've looked ... the central one (#3) has a definite crack in the oblong base on both the long sides ... I'll get the camera back out !! - better photos hopefully ...

Guess I'm driving the clit to swidnod .... :(
Now do I buy one for t'other side as well .. and get the job done all at once ??
-
No direct experience of such things but would 'think' that a possible source of short/breakdown. If the plastic/bakealite is like that externally may well be further probs inside. A CP is about 120 notes (cant find the receipt from andyC at the moment, memory is shot these days) so cant confirm.
I put new plugs in as well and, on recommendation of MarksDTM, used twin cores rather than quads.
-
mmmm I'm thinking that as I'm off to french France next week, and again in July, an extra £120 notes to do both sides might be worth it inn the long term .. they've both been in there many years and 125000 miles, and I'm not about to pull the 2/4/6 bank just to look .. if I go in there its a new CP and plugs ......
-
Plugs have done 54000.
Obviously worth checking them while you're at it, and change them anyway. It could be that you've got a dodgy one after that mileage, or that it's worked loose.
-
£94 ish + vat on TC ..not in stock .. so ordered both I'll spend an hour taking the 2/4/6 one out and fit new plugs and new coil packs tomorrow ... deep joy .. :(
-
Any evidence of corrosdion or brittleness on the wiring to the CP?

None noticed .. but I wasn't looking TBH .. I'll check when I take out the other one ...
-
I only mention it, because I'm quite sure, having replaced both CPs and regularly changing the plugs, that my persistant intermittent misfire is loom related :-\
Given the mileage on yours, the CPs are probably original, so perhaps due for replacement anyway. Can't speak for the plugs as mine are never in that long ::)
-
2/4/6 and plugs out .. :) 2/4/6 CP has some very tiny cracks , nowhere near as noticeable as the 1/3/5. For some reason the plugs look almost new compared to the other 3....
1/3/5 all have a small brown corrosion mark at the base of the ceramic part ... 2/4/6 are pristine .. :)
(http://imageshack.us/a/img96/8213/img7001k.jpg)
So, awaiting parts as they say :)
and if anyone is breaking/binning a 3.2 in the near future .. I need a new cable tray cover ... this one has now seen better days ( is that how you describe one in 3 bits ?? :) :) :) )
-
Its fairly likely that a 3.2 Elite will be being dismantled sometime in the next few months.Who by and when exactly is still uncertain but it will probably happen.A bit vague I know,but cant be more specific at the moment. ;)

fair do's ... :) but if the cable try lid is going spare .. please keep me in mind whoever is involved ... :) :)
-
As a reminder, when you refit the CPs be careful to ensure the plug is well clear of the socket at the back of the head :y
They have a tendency to get trapped underneath, and when you bolt the packs down it breaks the outer casing on the plug ::) if I impart one useful thing today, let this be it :y

Noted and thank you ... not a lot of room on the 2/4/6 side is there !!
In answer to your previous Q .. no sing of damage, brittleness, or anything to the cables to either CP ... on the small parts of the cables I can actually see !!!

(http://imageshack.us/a/img96/8213/img7001k.jpg)
That brown is a sign of things in the plug wells that probably shouldn't be there, or plugs that have been in a lot longer than 2/4/6 given the difference.. It could be a sign that oil or something similar has been in there:

Could be down to a plug on that bank that wasn't sealing well, allowing exhaust fumes by. :-\

They were all quite tight, not overtight but needed a firm push to start undoing. Lets hope the new CP's solve the problem .. can't think what else it could be .... :(
-
It certainly sounded ignition related, so agreed. Coil packs or plugs.
Mine has occasionally thrown a misfire code recently, and is on original coil packs. ::)
-
The brown could have been as simple as a slightly less-well-sealed rubber seal on the coil packs letting the atmosphere in, I suppose; the general oil vapour (or maybe it's only mine that has that given the state of the rocker seals ;D) and dirt would soon cause the brown..
-
.. ... in a moment of boredom I decided to actually take off the rubber seal around the 1/3/5 pack and have a look ... I was surprised to find this .. which I initially thought might explain a lot, until I realised that was all round the "1" end and the codes I got were 0300, 0303, and 0305 !!!

Looks like new coil packs wouldn't go amiss anyway :y

Reminds me. That cable tray in my garage is supposed to be on TBE... ...but then changing the CP/plugs is easier when cable tray is in garage ;D

Do you secure the cables in any other way when you "forget" to replace the tray ?? or just leave them dangling ..... :)

Mine stay prettty much in the tight form that they do when cable tray is present.

mmmm might just see what that looks like then .. :) Parts now in hand .. as soon as this shower stops I'll be out to fit them .. :)

Sorted .. 2 new coil packs, 6 new plugs .. :) Cable tray back in :) and lid held on with 3 cable ties .. :(
Just got back from a 20 mile test run, not a beat missed, including some high speed bits, steep hill starts and a bit of playing with the sports button .. basically tried to put it under heavy load ... all seems OK to me :)
System was reset before the run, just to put the light out and to check for any new misfires really .. but on return the readings are (whole run done on LPG as that needs a better spark and I thought would show up any problems faster) :
SHRTFT1(%) -7.8
LONGFT1(%) 5.5
SHRTFT2(%) -7.8
LONGFT2(%) 3.9
SHRTFTB1S1 -7.8
SHRTFTB2S1 -7.8
Now, if I knew what they mean't ......... :) :)
Any how .. reasonably happy hector until I look at the parts bill ... £238.18 (inc VAT) :( mind you .. without TC it would have been £322.34 (inc VAT) so I guess that's covered a few years ABS membership .... again .. :)

Owch :o Hopefully that will keep it going for a good while now :)
-
Always worth having spares, I bought a pair of 3.2 coil packs for £20 I think off here. That said I'll only buy ones that were known and working.
They are a bit of a gamble but worth it I think :)
-
good result,as said should be sorted for years now :y :y

Out of interest what's the mileage?

Thats good going, even more so that its been running on LPG for a good chunk of that. I'm still using the original coil pack from fatherT's 2.2, as we swapped that over as a test. So about 120k old now, his has got a new one has mine started to degrade at 110k.
-
Not really interested in the snapshot of the Short term trims, only usefull dynamically. The Longs are drifting a bit Entwood. Not unusual on LPG.
Can you do another code clear (which will reset trims hopefully), then do a 10-15 mile run on petrol*, and report back Long Term trims for both banks?
* Sorry to use just swear words ;D

TBE's 2/4/6 bank was replace at around 60k, initially with a 2nd hand part that misfired worse than the faulty one that came out, then with a brank spankers Bosch one.

What I'll do with spare ones I have, is keep them in the Elite when its in daily grind (after i've tested them of course) - They will be used as a get me home spares. :)

What size tool box do you carry as well !! Nothing fancy needed I know , just that quite a few different pieces seem to get used !! .. maybe moving the LPG bits made it seem worse ...:)

As requested... petrol selected, codes reset, 14 miles later ...
LONGFT1(%) 3.1
LONGFT2(%) 1.6
still the same "difference" from LPG side1 about 1.6 higher than side2 .... what's causing that .. ?? :( Awaits the expert to tell me .. :)
-
Ooooo, thats not great :o
Can you reset codes again, and immediately then check Long Terms, check that your reader is resetting trims?

Will do .. but what is the problem with those sort of readings ?? And would it make any difference that the mileage done to get those readings was noy "continuous" .. but involved 3 stops and starts ?? ... IF so I'll do the reset then do a 20 mile non-stop run and retake them .. :) but after the GP has been on ..(and I've managed to miss the news all day so have no idea of the result .. :) )
-
OK .. just done ... full reset and check that both short- and long-term trims all went to zero :y :y :)
19 miles continuous drive, mixed town and 5 miles of motorway at 75 (ish :) ) (no problems seen or felt)
Home and read long term trims
LONGFT1(%) 2.3
LONGFT2(%) 0.8
so still a difference ...1.5 (was 1.6 on both previous readings) ... but I'm guessing the 2.3% reading is still too high ??
Causes please ?? (as I know nothing :( ) [googling just gets me even more confused !! some pages say LONGFT should be less than 2% others say up to 5% is OK !!! DOH :( ] )
If my understanding is correct, bank 1 is running slightly lean and fuel is being added .... or are you hinting that bank1 lambda/cat "may" have been damaged by unburned fuel during the 5 minutes it had to run t'other night until I could stop somewhere safe ??
Easily Confused of North wilts ... :)

On petrol, it should stay at 0%, +-2%. As LPG is a bit barbaric, they drift off a bit.
At idle, are both BxS1 O2 sensors flicking at 0.5 - 1Hz

Yup :y :y :y :y
+-2% ... ?? +2.3% is very close so hopefully nothing too serious ... perhaps it needs a longer run than 19 miles to sort its life out ??
I'm doing best part of 1000 miles next weekend - on LPG for definite :) - Paris & back .... :)
-
For petrol, I'd expect long terms to be pretty much 0%
For LPG, ideally keep them between -10 to +10%

OK .. I'll check them after the Paris trip this weekend on LPG.
Appreciate your teaching :) :y :y :y

If you get a stored trim code, its exceeded 20%. If you get an EML, its gone beyond 23-25% (I can't say accurately, as not that many are that bad)

Never seen one of them, only codes I've ever seen on this one have been the 0420/0430 which I expect to get (again) within the next week (French LPG) and the 030* mess I got t'other week.

Time you relocated the O2's then Nige!
The major issue we have on the diag here is the addition of the LPG system. As most will know, LPG piggy backs onto the Petrol ecu and modifies the injector pulses for use with LPG based on a few simple sensor inputs.
A downside of this is that there is the need to manualy map the system plus its a compromised approach hence its easy to see an LPG setup showing fuel trims which are not ideal.
It would be very good of the LPG setups would also monitor the O2' sensors and provide trims for the system.

When are you free ? :) :) :)
On a more serious note .. Thanks for the info ... as mine is a BRC Sequent 56 system there is no manual mapping facility available to me, I believe - from reading the stuff I downloaded some while back - that the BRC "self maps", but I'm not 100% certain. According to that paperwork the ECU does have lambda inputs. I do know it has not been remapped since installed - I watched the last couple of "services" (3 & 4 years ago) which comprised of a filter change, a "sniffer" around the pipework, and plugging in an analyzer to the OBDII slot and stating "no problems" .. for which I was charged silly money. I've done my own filter changes/sniffs/and OBDII checks ever since .. :)
The LPG installers in Swindon (not the ones I used for conversion) have recently taken on the BRC franchise, do you think its worth having them "remap" or "recalibrate" the system ?? It has been in 5 years and 53,000 miles without one ??

Relocation of O2 sensors is much easier for me to do now thanks to the aquisition of a plasma cutter.

Thats convenient... ...you're only about 80 miles from me :P

Perhaps we ought to form a queue .. :)

I'm closer...... :y
;D
Mind you, I not got 0420 or 0430's yet!..... My last 3.2 was the first one reported on here to get them though!

The worst part about re-locating them is removing the front pipes.

That's the worry ... could be a 20 minute job or a 2 hour job ... makes asking someone to do it for you either a favour or an imposition, and you don't know which until the point of no return !!

Worst case scenario is drilling out the centre pipe bolts but, as the cat is being removed and given a good pillar drill thats not a big issue.
So parts required are:
2 off Lambda bosses
2 off Lambda boss blanking plugs
2 off front pipe to manifold gaskets
4 off centre section to front pipe bolts.
2 off new front pipe to manifold nuts (often not needed hence only two just in case!)
Then I would say 1-2 hours typical (less or best case)

Jekyll and Hyde syndrome i'm afraid, I'm either driving in kickdown or gently trundling along with the traffic flow!

so .. a couple of these to cover the first two items .. £13, gaskets are what .. £10 ?? bolts and nuts £5 ?? so less than £30 in bits ???
fuel to get to wherever, and a couple of hours labour money ..??
Have I missed anything ??
(and should I talk seriously to you ..... :) )
