just getting used to the quirks on new ride. Sometimes when you start the idle will fluctuate 400-1400 rpm .. last for a about 10-20 seconds then go normal. What quirk is this? 2000 GA GT.. Thanks- greg

could be TPS or IAC also, maybe the O2, or MAF maybe as well? clean the maf and check the other 3 with a scan tool

well the car will go into a different setting when the PS pump is involved, it uses default values because of the additional load put on the engine.
