Problems with dying at idle and when letting off clutch.
When I let off my clutch or stop at lights my car usually nosedives in RPM's then shoots back up and then usually dies. I have replaced the TPS and Idle Air Control Valve. It just seems like the car doesn't know where it should be for idle. The strangest part is that this problem only happens about 60% of the time. The rest of the time when I let off the clutch the RPM's hang like they should and the car doesn't die. Any ideas?

do u have a hand held tuner? u can check for codes. U might have one. Did u recently do anything to the car? Besides replacing the tps and aic. Do u have a boost gauge? What does that read at idle? Do you any other sensors, like a air temp sensor that is hooked up for the turbo system that is connected via maf wires.

With all your mods, it sounds like there is a problem with your tune. It may have already been tuned and ran fine for a long while, but it's not unusual for a little quirk like this to show up sometime down the road, especially when the weather changes.
