I thought replacing my O2 sensors would fix this problem, but I guess I was wrong. The engine will rev to about 1800 rpms when I push the clutch in, especially after highway driving. Sometimes it will stay at 1800 for about 15 seconds, other times it will drop right back down to it's normal idle. If I tap the gas in neutral, I can get it to do it slightly. It seems to correspond with how hard I had just pushed the gas. Like if you just rev the engine, it will drop, go back up, and drop again. Very strange... I cleaned the IACV and throttle body, timing is set at 13*, and the idle is set at 650 rpms. The throttle position sensor is within specs, and I'm out of ideas. Any ideas from the Nissan gods would help!
FYI, the car runs like it should, good milage, pickup. Just this damn revving when my foots not even on the gas.
