ok so my car still has a missfire on cyl 1 , 3 , 5 been told it could be a few things like plugs and coil pack ,, changed the plugs and did the coil pack today and its still missfireing
im so pi**ed off with the car now its costing me so much and its still not right ??
can anyone help please ??
thanks so much Ben

Definately sure you've connected the leads up correctly and did you use a new DIS?
-
did you get a new dis pack? check the plug on the wire make sure that it good and clean. also check the ecu main plug is in tight. and injector relay.
-
yeh brand new bosh one ,, connecter looked nice and clean to me ,, so lost as what to do as i need the car for work and its just costing me so much to fix but nothing is going rite ,,
would it make any difference if i put the code reader on it and clear the errors becasue when i checked it a while ago it said miss fire etc but never cleared error memory when i fitted new bits ??
-

No leads on 3.2 its coil pack ;)
Do a pedal trick and post up the codes :y
-
dose the eml light still come on, or is it off?
-
out of interest, do you have K&N panel or cone filter fitted?
-

How about the leads themselves? They may look new but the could be brittle on the inside.
There are no leads on 3.2 or 2.6
-
ill run the code reader 2mora and let you know all the codes ,, no its running standard air box and the eml is off , never came on just got the missfire
-
Sorry if I'm asking the obvious, but you don't have any water getting in there from the scuttle?? Took me ages to find it on mine (got there in the end thanks to Tunnie :y) although mine was on the other bank.

where are you getting the missfire info? from the pedal trick? or code reader? exactly what codes are you getting?
missfire codes start p030* iirc
-

you can read the codes yourself here,

although you do need a code reader to clear them.

spray the leads both ends with wd40 to make sure they are not arcing across each other

so how does the DIS-Pack get a spark to the plug with no lead???? (seriously.... ????? I've not yet owned a 3.2 so have no idea how different it is.... )

There is no DIS pack, there are coil packs which sit above each bank, the 'lead' is part of the coil pack:
This is a 4 pot version for the 2.2:

One coil per plug.
The dis packs on the 2.2, 2.6 & 3.2 are a strip of plastic wth 3 (or 4 on 2.2) little ignition coils that sit on top of each of the spark plugs.
When in place it just looks like a cover strip down the middle of the cam covers.

It isn't mine ::) I copied it from the maintenance guide :y

so now i get it.... clever.... i presume it's less prone to corrosion fromm leaky things like HBV and stuff then? reliability improvement????

Err well not really, they don't seem to be any more reliable, heat is a problem i think for them. I replaced mine at 105k
-
Could it be that the idea is that since it is essentially low-tension right up till the last minute the leads won't wear out and therefore you don't have to get burnt trying to shove your arm up past the exhaust to fiddle blind with the DIS pack from h*ll?
-
out of interest, do you have K&N panel or cone filter fitted?
What is problem with these filters.
-
out of interest, do you have K&N panel or cone filter fitted?
What is problem with these filters.
Panel filters are oiled, and kill the MAF.
Cone filters are just plain stupid, they reduce power, suck in warm air rather than cold and actually reduce performance

I think oiled filters are available as either panel or cone filters.
They can work well with carburetors or throttle bodies but they mustn't be used with a MAF because particles of oil can get carried over to the MAF sensor and contaminate it.
I agree that the standard air intake should get cooler air than a cone filter would but I don't know if it will make that much difference if the car is moving :-/
-
thanks for all the replys everyone ,, i read the codes on a code reader dont remember the numbers now but it said missfire cyl 1 , 3, 5 , car must of been running in limp mode ,, i cleared the error codes and car seemed to run alot better then ,,, i took it for a long drive yesterday and all was fine till about 20mils down the raod it went back into limp mode again and started to missfire ??? anyone have any ideas ??? im thinking the plugs or one of the plugs on 1,3,5 could be faulty ?????
-
I've had this on one of my classic cars, all new ignition components and still had a misfire. turned out to be the small silver cap on the plugs were loose so they weren't allowing a full spark through. Tightened them with pliers and all was well again. Not sure if that's it but an easy one to rule out ;)
-
ok so got some more new plugs today got them fitted went for another test drive and still missfires ??? so all in all ive done cam cover gaskets , spark plugs twice , coil pack , cleaned the MAF ,,, and there is still a missfire on cyl 1,3,5 ,, what else could it be im at my wits end and just feel like getting rid of the dam thing lol
ben
-
checked the bits on end of plugs they are tight :( so still no idea what it is ????
-
when the plugs were out, did you notice any oil or water contamination anywhere? Are the ends of the coil pack rubber plug covers ok, or showing signs of wear, breakdown etc? :-?
-
yeh when i first looked it had oil on them but i done the gaskets and everything nothing else seemed wrong apart from that ,, so still dont know ??
-
i give up with it lol costing to much money ,, anyone want a 3.2 omega specail with LPG
£1500

do pedal trick
read codes
post codes
-
had it on the diagnostic and its just says missfire cyl 1 3 and 5 :(
-
are you winding me up?
-
no why ??
-
Someone help this kid before he does something drastic.
I was helped when I was feeling like he is.
Come on folks
James Elite Pete Daz, try and help the kid, he must be at his wits end to put it on Pistonheads.
-
trying, refuses to be helped
for the last time
do the pedal trick
-
Methinks a quick trip from Grantham to Nottingham so MarkDTM can put a tech2 on it and get some live data is the first step.
There is no point in changing parts willy-nilly and in hope ... the rules are simple ..
Diagnose
Rectify
Nowhere in there is the word "guess"
:)
-
oh yeh i am im so fed up with it now ,, spent so much money getting the clutch done :( now this ,, spent a fair bit trying to fix this problem and nothing ,, so ive about had it lol
-
Or Dispack!! :y
-
Or Dispack!! :y
Its been said before .. I'll say it again .. LOUDLY
[size=16]3.2 V6 ENGINES DO NOT HAVE A DIS PACK[/size]
:) :)
-
has a coil pack m8 :y
-
so new plugs are in, no oil in the wells?
Still getting 135 miss-fire? Points to coil pack.
Unplug the MAF, take it for a drive, if it still miss-firing. Its coil pack on 135 bank
-
Or Dispack!! :y
For the [size=20]4th[/size] time, it has no dis pack, its coil pack above the plugs.
spray the leads both ends with wd40 to make sure they are not arcing across each other

No leads on 3.2 its coil pack ;)
Do a pedal trick and post up the codes :y

-

actually has 2 Coil Per Plug modules if you wish to be totally accurate.
Do the pedal trick .. post up all the codes you get.
PM MarkDTM arrange to visit him for a live data reading
Stop guessing
Take car off pistonheads.
Simple ...... :)

Earlier posts you did not give these codes? Only missfire on 135 bank?
P0301 Cylinder 1 Misfire Detected
P0302 Cylinder 2 Misfire Detected
P0303 Cylinder 3 Misfire Detected
P0304 Cylinder 4 Misfire Detected
P0305 Cylinder 5 Misfire Detected
P0306 Cylinder 6 Misfire Detected
Both coil packs will not fail, and as long as the plugs are clear of oil, if you getting miss-fire across both banks, suggests MAF.
Unplug it and go for a drive

also does not explane limp mode

bank 1,3,5 pack ,,, yeh its off a bosh reader i have ,, ive cleared the erros before and it was fine for about 20 or so miles then started to missfire again ,, now does it offen even after errors are cleared
i would do the pedal trick but car is at my girlfriends house

yeh only missfire on bank 135

bosch are shite, as are snap on.
often give conflicting info, they dont seem to have the complete code list ime
Strongly sugest pedal trick when possible. its free, to confirm accurate code read.
If still 0300 1/3/5 drivers side, check wiring and plug to coil pack (no dis pack or leads) for continuity or damage.

checked plug and cleaned it and wires and all seem fine ,, i shall go do the pedal trick 2morrow after work and see what i get and post results ,, i would drive the car to nottingham to see mark but as car is running like it is at the momet its drinking to much fuel and my pockets are a bit empty at the moment :P

ok, also check ucu plug fully home/no corrosion on the pins while your there.
if you have the same codes via pedal trick with new plugs and coil pack and good wiring, then as Entwood says, it needs teach 2 to investigate further, Mark dtm is nearest you, he is far cheaper and better than any garage.

cant tell anymore without further diagnostic.

Whats Grantham to Nottingham?
30 miles.....??
I do it in 45 mins in my 18t truck at 40mph all the way along the A52, so I would say its a 30 min drive in a Mig.....
People are trying to help you buddy but you got to want to help yourself too.....

Did you say with LPG? What plugs have you put in? I think the MAF idea may be plausible too. The other thing that is ringing in my mind is whether the timing belt has jumped a tooth. You'd get erratic running but I don't know whether it would register as a misfire.
Also,I wish you'd stop bloody quoting me. I deleted the second post straight after the first as I realised it was a mistake and Tunnie had already flipping quoted me. :D

-
how would maf fault affect one bank though? and would expect a fuel trim code if so...?
belt issue possible but why would it clear when codes cleared and then play up again after 20miles, or whatever it was?
cat issue would also raise a code imo
-
should also ask if any other work has been carried out that may have had an effect on the issue?
-
Just to question what may be obvious..
1,3,5 bank is on the drivers side (right hand drive ;)) - you did change that one didn't you?
-
Hi,
I have been following this thread with some interest, as this was the first problem I had when I bought my car.
I don't think I can add any thing much to what has already been said.
When I had this problem, my code reader identified which cylinder was miss firing, on examination you could see the cracks and iron laminate swelled on that plug unit.
What puzzles me is your 0300 multi cylinder misfire.
I would be looking for bad earth connections on supply to CPP unit or on the injectors on 1-3-5 bank.
I don't like making guesses, but it does sometimes happen that a new / replacement part is faulty.

well ive checked a few things over today and all seems fine really ,,, been for a drive today with the MAF unplugged ,, drives well now ,, after a few miles it did go into limp mode again and missfired so i stoped the car and restarted and was fine again ,, so it coul be my MAF that is no good ,,, but i think it is something else aswell as the MAF ??
yeh 135 is drivers side and thats the side ive done all the work on :y
