I just have my head rebuild and new head gaskets because they blew i dont think that has anything to do with it but i was wondering if anyone will know what can cause this. I have a pcmforless chip that worked perfect before by head gaskets blew. After the heads replacement it will not idle right when i first turn it on till it gets a warm. While its first turned on it jumps in idle and is lower then put on the chip. After the car is warm and been driving for like 15 miles then the idle goes to whats on the chip at 1000 at park and 600-750 in drive.
