Ok, latest update - checked and set the TPS to read 0.5volts at closed throttle and it reads 4.23volts at wide open throttle. Still no change and occasionally hunts at idle when warm. Removed the pcv valve and cleaned it. Can anyone confirm that when the pcv valve is shaken, there is something moving or rattling inside? How would one know if it is faulty? Anyway, cleaning the pcv did not make any difference.
Anyone have any other ideas what could be causing the occasionally hunting at idle when warm. The rev needle hovers between 0-1000 rpm and sometimes the car stalls. Rossco, any ideas????
Cheers
