Misfire Problem On V6

[wood73]

I have put up with the steadily worsening misfire until i can bear it no more, the car had become undriveable.

today I changed the leads and plugs, it was slightly better but still missing like a bu***r!

the plugs out of the back of the engine looked fine but the front three were badly burnt (the electrode was half the size of normal)

can anyone help? I dont want to go to the expense of a coil pack if its not going to make a difference.

cheers

Mine did just that and i'm afraid to say it was the coil pack. Get it out in the daylight and look for very faint track marks between the 6 pots. You need a good eye to see them, but if they are there, it certainly buggers up the running of what is otherwise a very smooth engine

I just recently changed my coil packs, got them off ebay 70 quid for 2. I have posted a link to it somewhere on here... If you search for it I am sure you will find it... If not I will try to dig out that page myself.

 

You can pull the leads off the plugs or the coil pack and see if there is a change in the engine to determine if it is the coil pack, and which one..

I bit the bullet today and bought a new coil pack.

I fitted it but it made no difference! i was standing there baffled playing with the leads with the engine running and my other hand was near the wiper when i got a shock and noticed a spark from my knuckle to the wiper but only when touched the 1 lead, so i took it off and replaced it with 1 of the old leads and hey presto perfect, out of interest I put the old coil pack on and it was fine.

so I now have a brand new
