Why is my car idling @ 1500RPM?

What's up skyliners

Would anyone know why my car is idling @ such a high RPM? (1500RPM)

It seems to be constant, and it's been like that for a while now. Sometimes the Revs will even bounce, usually when starting up the motor, or coming to a stand still from acceleration.

Besides that, the engine seems to be running smoothly. I can even let go of the clutch in gear 1 without having to step on the accelerator, and it won't even stall on me.

Was fine until i was thrashing it up and down the street one day. Left it there for half a day then it happened. Tried cleaning the AFM. Same same.

Could be a vacuum leak? i highly doubt it. Any suggestions?

Cheers.

Skyline R32 btw.

vacc leak. Re tune.

I agree same issue with mine. Tune or AFM or aftermarket fuel pumps sometimes make this happen!

AAC valve or TPS are the usual suspects when this happens.

was gonna say AAC valve, could also have a look at water temp sensor.

Cleaning the throttle body fixed mine
