could a faulty or damaged IAC mess with driveability,
I have a 85 duke 5spd
just a few short weeks ago i was cleaning out my TBI with some carb and choke cleaner and i kinda drowned the IAC port. I thought nothing of it. but a week after that my engine check light kept coming on and the car would idle iradically and almost stall. when i am driving. it bucks and jerks all around. it even bucks when decelerating. is it and IAC problem or a O2 sensor problem. I replaced the TPS thinking it would fix it but it didnt. I am so fed up with this car, but i love it too much to let it go. any help is appriciated (would a vacuum leek cause such a problem?)
