2002 isuzu rodeo, 3.2L, 5sp manual. The car is idling very low and stalling. If I turn on th AC and stop it will completely cut off. If I leave the AC off and stop it will nose dive almost to zero and then bounce back up to about 700 rpm. I've taken this car back to dealer twice under warranty but they did nothing. Now that the warranty is over I took it to a local shop and they replaced the EGR valve. Didn't help. This problem only last for about 20 minutes, after that it runs just fine. I have no check engine lights.

Sounds like a slow or malfunctioning Idle Speed Control Valve. It controls the idle for the computer. Might also want to try cleaning out the throttle bore around the butterfly with some carb spray and a rag
