Why does my Nissan D21 hit 2500 rpm?
The fact that it hits a 2500 rpm rev limit is odd but we can try to fix the idle first and then come back to that. On the idle control valve when you turn the screw to the left it allows more air into the engine at idle which will lean out the mixture. When you turn it to the right less air enters and richens the mixture.

What is the idle control valve on a Nissan D21?
On the idle control valve when you turn the screw to the left it allows more air into the engine at idle which will lean out the mixture. When you turn it to the right less air enters and richens the mixture. Make sure the Throttle position sensor is disconnected as this will allow adjustments without the computer interfering adding extra air.
