    Ok, I have tested the ignation control module its good, Even used another one.

    Swapped out the coils and wires with someone elses and put in new plugs.

    I even did a compression test and all 3 front cylinders where 115ish.

    My missfire is really bad at an idle. but clears up with throntal. but soon as i come to a stop it misses pretty good and i get a nice white smoke screen out the back.

    Only thing i can think of is my intercooler core is leaking? its a thrasher ic so its not like zzp and plaged with this issue. anyone else have any ideas?

    Sounds like you have some unmetered fuel. I would suspect a leaky injector

    Don't care how old it was, I'm curious to find out what happened. I'm sure other people that read instead of just ask questions, may wan't too know as well.
