ok i've had my sc now for 4 days its messed up 3 times....the symptoms are weird... ok when i'm driving or the car is under a load or if i'm just running the car hard it runs fine no hesitation no nothing but as soon as i come to a stop at a stoplight or something it idles at like 300-400 rpm and sputters and will eventually just die out...i took the IAC off the other day cleaned it with carb cleaner and it ran fine me and a friend of mine went playin around on the way home from his shop well i started doin a doughnut in this old parking lot and hit a pot hole which did bust my pressure hose from the power steering pump.... so i know what the problem with that is but as soon as i came to a stop again it started to sputter and cut off again
