This car is really starting to piss me off!!! The dealer replaced the IAC valve under warranty, 2 months later Im stuck the the same problem. No more warranty so I replace the IAC valve and the TPS, 2 weeks later, the problem is starting again.
Please don't tell me to try the TH fix because I can deal with throttle hang...this is throttle rise. The RPM's will go up when you put it in neutral and your rolling, then when you come to a complete stop the RPM's will drop down. It will idle perfectly at 600 - 750 but then it will jump up to 1100 or so and drop back down. And it will just go up and down. It pisses me off so much when Im at a light, so I wind up taking off like a mofo. And then there's other times where the car runs perfect.
What else could be causing this to happen??? Please help...
