Ok I just got my car last week, and I'm still trying to figure out any bugs that are wrong with it. I already changed the plugs and wires. Neway the problem... The car drives perfectly fine, and it hows power and get up, until you get to a red light. Then it starts to stutter. I'm think maybe a coil. If not that a hose may be off somewhere... Anybody agree with either of these? Or could it be an O2 sensor?

What? You've had that car forever. Didn't someone rearend you? You get a new car? I'm confused.....

This is my New bonne I'm talkin about.

Wat year is it? The 93? Just wondering if it'* the IAT?

Mine used to do that some, too, til I tightened the bolts that hold the throttle body on...

the wire on the IAT is hooked up. I don't know about the TB. Surprisingly it is clean. So it saves me time on doing that. it also doesn't seem like it has a much compression. I think I may have a exhaust leak somewear causing it to lose some power. I don't know I need to pull it up on ramps and jack the rearend up and check it all over since I bought it from a private seller.

Do you have a ohmeter?? Does the gurus here know if the IAT sensor is the same for 93 and 97?? IF so.. I will email you something just to ensure it'* not the IAT sensor. I have researched a lil into the IAT sensor as it will not throw a SES if it'* off calibration.. it will only throw SES if it'* open or shorted.. which means it has completely failed. I don't think it would be your issue.. but meh.. at least you know for sure that it'* not contributing to it.

MOS brought up a good point too.. if the gasket is leaking air pass the TB it might have similar results.

I'm assuming you don't have your MAF screen removed correct?

My car does the same thing once in a while. . .

An EGR sticking open will cause a rough idle.

Mine would do the same thing REAL bad until I cleaned the MAF sensor and the TB an IAC then it only does it when the motor get'* really hot, because the cooling fans only work on highk, the Low speed is burned out. But when my engine gets really hot (220-230) sitting in a parking lot, the heat soak starts making my car stutter until I can get the temps back down to 195-205.
