here is what i have in my car:
stock 91 turbo awd ecu
stock fuel system
stock 14b
greddy type s bov
3in apex exahust system with n1 muffler
cometic headgasket
...thats all i can name that really has anything to do with the motor or anything that has to do with this problem..
i checked all piping and seems to be good...timing i will do soon (once this snow storm is over and i can get my car to the garage)...as for ecu caps, the ecu is doing fine...i've been able to pull with this ecu w/out this problem occuring. this is a first.
one thing i should mention though. i don't know if it has anything to do with the subject but yea...i bought another ecu recently and the guy said that the caps needed to be replace soon. i put it on the car and the same thing happened but at 4000 rpm...it was staggering and backfiring...etc.. than i switched it with the normal one and now its happening to that one...(thats the one i have on now) just a thought. if it matter.
thanks guys.
