The shops cant help me and i dont have a clue what it can be but my 86 gt always breaks up when at steady throttle... the timings fine and i dont think its the injectors because it doesnt happen when im accelerating... any ideas?

My modifications are:
Full exhaust, CAI, 70mm TB, Cobra upper and lower intake manifolds, underdrive pulleys

tfi modual? does the motor break up when its cold or only when its warmed up. the tfi modual is known for failing when it getswarm

loeryder21

yeah it runs awsome when its cold but once it warms up is when it breaks up. probably dumb questions but whats a TFI module?

loeryder21

i dont think its my TFI module because my car doesnt stall out and starts fine everytime. all thats happening is that at constant throttle it breaks up and if i give it a little more it clears up and runs smooth again. I dont know what it can be i went to like 5 different shops and they dont know either

Try swapping out youre mass air. Thats kinda what my car was doing.

and if you dont have one to swap with, they make a spray specifically for cleaning the wires in your maf. you can give that a try
