As before....Getting codes 0300 .....and 0305 and 0306.....with the pedal trick......2.6 running rough especially at very low revs. EML light will not go out.
Banged in a new set of plugs. No difference whatsoever... :-/ Still getting the same codes.
I've just fitted a brand new Bosch coil pack to the 1..3..5 bank (£61.50 inc postage)Everything is still exactly the same. Car running rough EML light on and the same codes....
Any ideas please?.... :'( :'( :'(

0306 is the passenger bank

I know Rob. I'm just trying to sort out the problems on the 135 bank for now. I was hoping new plugs and a new coil pack would sort It out . I was then going to look into the problem on the 246 bank... :-/

but you still have 0306, a mis-fire on the other bank of cylinders. I think you'll have to bite the bullet & buy a coil pack for the other side too. ;)

That was to be my intention Andy. But bearing in mind a new coil pack has not solved the problem on the 135 bank........ I'm not convinced I want to go down that route at present. The old saying "throwing good money after bad" comes to mind... :-/ :-/ :-/
-
this is about your 6th thread on this now...lets just keep it all to this one and get some continuity going.....
Is the 246 bank as rusty as your 135 photo was?
are your camcover gaskets leaking?
-
Before throwing money at coil packs, have you done the basics - compression test?
-

gives some of the previous threads....please bookmark this one now, and just update this, may stand a chance then :y
-
some of your prev posts show the 246 bank in a not very good state - thats gonna want replacing sooner rather than later anyway judging by the rust.
one other (unrelated) question - are you levering the coil packs out....or using (plenum) bolts down the bolt holes to lift em out as per the maint guide? may make your life easier :y

Mr Jimbob......135 did have oil in the plug holes.( mainly in plug hole 5) I removed this and it has not come back since . This is why I have yet to get round to sorting the cam cover gaskets on this bank. "
246 coil pack is as bad as the 135 pack......rusty with a few bulges and splits in the plastic casing..... :'(

Nope James. I do not have a compression tester. The results might be interesting.... ;D :y

right, so you have had 2 dodgy coil packs
you now have 1 good (so should have no 301, 303, 305) codes
and 1 old (leaving you open to 302, 304, 306 codes) if it is faulty.
or a wiring fault elsewhere
or something unrelated.
do you have "My Naff Code Reader" or similar to clear codes / get live data?
does it run any better if you disconnect the MAF?

I lift them out with two bolts of the correct size...(As Chrisgixer suggests) I I do not try to lever a screwdriver under the rubbers..... :y

No "My Naff Code Reader" (Whatever that is?)
MAF?.......Not familiar with this......but I'm learning....... ;)
Also ......I have tried three different plugs in cylinder five just to make sure that it is nothing as simple as a faulty plug..... :y
I have code 0300 as well ......is that relevant?
-
I'm slightly surprised that Plug 5 is bone dry when I take it out. I would expect it to be wet (if it's not sparking).
Car runs roughest between 500rpm and 1500 rpm (About 4 cylinders?) it smoothes out after that and will pull to the 6700 red line but without any real vigour.... :-?...Hmmmm
-
i believe if the plugs not sparking the ecu will shut off the fuel to that cylinder (well it does on my wifes polo!)
-
well "My Naff Code Reader" is laptop based diagnostics that talks to the car (but cant discuss obtaining as its a rip off of some £700 software) which can be handy, gives logs such as jamesV6CDX posted in here. Also reads and deletes fault codes, which can be handy with intermittant, or problems you think youve fixed as you know the codes has gone, and can then see if it returns.
MAF - bit of a long shot given the symptoms, but that can be problematic on 3.2 and 2.6 cars, look lie : http://cgi.ebay.co.uk/Mass-Air-Flow-Meter-OPEL-Omega-3-2-00-03-Y32SE-MAF-/120668177128?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item1c186242e8
and sit just down from the airbox, unplugging them causes the car to run on a default map, so if they are sending duff info, can rule them out as a possibilty.
Apart from that, hows the car serviced? filters newish? or end of life? ie Air and Fuel. Have you run any injector / fuel system cleaners through?
-
Opti, you need to dis count the obviously damaged "looking" but not necessarily faulty coil pac(s) is there anyone near you that will help you swap in some known good ones? Another oofer perhaps. Or ask the breakers on here?
And it has to be said, somebody with your post count should know better to post multiple threads on one topic/issue. Htf are we meant go diagnose with half the info missing?
Anyway, plugs and cp are new on 135? so now your going to have to bite the bullet and tackle 246 bank. For all you know(from memory) no 6 is falling apart in the bore and destroying the engine. Get in there and pull 6 plug out (if not done already ???) and hopefully swap in a known good cp at the same time. Dirty hands time!

Oil and filter changed 7,000 miles ago.
Air filter. I have checked this and it seems pretty clean and does not look like it needs changing.
Fuel filter?.....Not sure where this is.
By fuel system cleaners do you mean the gunk you add to the petrol?......if yes ...then no.
I have located and unplugged the MAF. The cars runs exactly the same. The pedal trick gives the same codes....0300....0305.....0306. I have reconnected it.
For Chrisgixer. I have replaced all six plugs Chris. Originally Bosch Super.....replaced with GM 011. As you say Plug 6 was a bas*ard to remove and looked like it had been in there since the dawn of time. I have left off the oil filler neck and the plastic casings holding the wiring for now as it makes lifting the 246 coil pack much easier and quicker to do
-
Ok,
imho, the car is overdue a service, I wouldnt let my oil go that long, but I wouldnt worry till this is sorted.
if the fuel filter has never been changed in your ownership, then it will be overdue, unlikely to affect this issue, but would add to your to do list.
Yes, gunk you add to petrol, like forte advanced formula gas treatment, stp injector cleaner, redex etc. again, prob wont really help here, but wouldnt hurt either.
you have these 3 codes....you may or may not have fixed 1 or more of them, I suspect you may only have the 306 as an active code, without a code reader, its hard to tell.
sounds like youve proved the maf is not to blame as well.
are you aware of anyone local with a code reader / deleter?
I would really want to be clearing out codes and seeing what is still present, if the 305 is still there (afaik you cant tell with just pedal trick) then its slightly worrying given youve fitted a new coil pack on that side.
-
I've just removed the 135 coil pack (again).......put the plugs in it and then rested it against the engine. Turned the engine over with the result of.....three nice big sparks
I then removed the 246 coil pack (again)to check the plugs. Number six was wet . I then fitted another plug and started her up. still running rough and still showing the same codes. The 246 coil pack has most corrosion on cylinder number 6. Coincidence?
Will my old 135 coil pack..( if not Donald Ducked) work on the 246 side?. They look identical to me... :y

I can answer that, no it wont work different firing order I imagine, I bought a second hand coil pack from SWVauxhall spares on fleabay for about 40 quid delivered, compared to the one it replaced it was in excellent condition.

I had a simular problem, with simular fault codes. A new coil pac sorted out my woes.
There isn't any loose electrical connectors or vac pipes is there?
What sort of a state is the fuel filter and air filter in?

On my facelift 2.6 saloon the fuel filter is located just inboard of the drivers side rear wheel. To replace you will need the new clips from Vauxhall, (about 50p each, maybe less), and a proper set of fuel filter pliers from Machine Mart, which are £16 for a set of three IIRC.
If you can make it up to me, (north derbyshire), then you are welcome to borrow my old dis-pac. I had to buy a new one as I had shagged one of the rubber spark plug boots, but counldnt get a spare boot for love nor money.
-
I got a new one for £75
Unless codes are cleared they stay
Plugs cause 030x errors as well
-
Shop around for dis, sure I saw vx parts warehouse do em for £65.
They are handed, due to the angle the of the plug well relative to the top body, the boots do not enter the head square on. Other than that I am not sure there's any difference? It "may" be possible to get a 135 PAC to spark in 246 if the seal is removed temporarily I guess, it'll be a fiddle though.

Spot on Chris. Yes.....they are "handed." I failed to notice that before. I'm now going to see if I can "adapt"my old 135 coil pack (which may or may not work) and try to fit it to the 246 bank.
I presume that it's nothing to do with the firing order of the engine that was mentioned earlier in this thread?......Worth a try...I think... :y
-
Firing order wont impact.
Note, you cant test a coil pack without a test plug (I do have one here).
-
Success.....sweet success. I had to remove the rubber seal but I have been able to place my old 135 coil pack on the 246 bank. I needed to remove the seal because I had to "waggle" it around to connect with the plugs .......and then waggle it again in order to locate the two securing bolts properly..... :y :y :y :y
The old girl started first time and then settled into a beautifully precise SIX cylinder idle that would put a swiss watch to shame. :y :y :y :y :y
She now drives perfectly all the way to the redline at 6700 RPM..... :y :y :y The EML light has finally gone out......although the pedal trick still shows 0300....0305.......and 0306 codes.....Why?
It seems that the 0300 and 0305 codes were old (non-deleted codes)......and the 0306 code was the only active code...(Gold star for Jimbob... :y) I should have guessed this as plug 6 was the only one that came out of the engine "wet".......due to the fu*ked 246 coil pack...... :-/
I now need to find a way to stop water getting in as the rubber seal is not there. But Other than that I'm a happy man.
Thanks to Jimbob .....Chrisjixer and many others who helped find a solution to this problem..... :y :y :y
-
glad youve finally got there.
personally find a decent code reader an invaluble part of a toolkit, makes things a lot easier when you know what the ecu is reporting.
So, your going to try and make do with the 2 x 135 coil packs permanently? can imagine a removable 'seal' would be tricky to make.

How much for a decent code reader/deleter Mr Jimbob.?
I will source a 246 coil pack......£61.50 inc postage for a brand new Bosch 135 was good value ..I think. :y

Well done Opti 8-)
I bought a Maxiscan MS509 following good reports from Nige (Entwood)
This has proved invaluable in identifying a fault on my Desmond and clearing the relevant fault codes.
It paid for itself on the first occasion I used it.
I'll get a link for it shortly.

yes, sounds like you did ok...
code readers start at around £30 upwards depending on you needs

Thanks for the link ..Z. It looks like a pretty comprehensive piece of kit.The price looks reasonable too.
I'll resist the temptation to ask about "your Desmond"....... ;D ;D ;)
-
I am curious about this.
Do you need a laptop?
-
MS509 is a stand alone device .. no laptop. no power cables .. just plug into OBDII socket and away it goes .. it is one "up" from my MS500 which has been "superceded" it appears .. but still works !!
:)
A list of decent devices .. but you can buy elsewhere .. however AVOID EBAY .. most are chinese clones and have problems .. genuine only IMHO .. :)
