@Carlijawan The problem with my idle was that the Idle Air Control Valve (IACV) and the Throttle Position Sensor (TPS) were not tuned to their correct base level. After disconnecting the TPS, then Adjusting the IACV down (turn clockwise) all was good again. Check the Factory service manual or 300zx websites for more info :-)
What does this mean? My 90 z32 always idles at 800-900. And recently it started to Idle at 1500-1600? I dont think its normal.
