Hey guys!

My V8 has a case of missfiring i think, and its more noticeable when the engine is cold. When I start it in the morning, it trembles until it warms up at which point the trembles decrease.

By trembling I mean small vibrations that come and go, as if the the sparks aren't igniting at the right time or something. I have just recently changed my leads to new toyota ones so i know its not that and about 20,000 ks ago i had iridiums put it and there ok too (S&LC said so). Can buggered coils cause this hasle? Is it worth fixing?

Mine does the same thing. You have to give it a quick squirt when you start it and it's fine. If your plugs and leads have been changed, could it be the CSI?

Do the engine revs vary when it's doing this?

Mine does sometimes. It only lasts about 3-4 seconds but it's very annoying! It's almost as if theres too much fuel going in or not a big enough spark to ignite it.

Peter the revs vary only for a small amount of time at the begining and only by 250rpm and by that I mean that the revs will be 1000 and after about 20 seconds they'll rise to 1250 after which the auto choke gradually drops the revs as the temp rises.

Should the coils be due for a change?
