Hi I have a 2001 a33 maxima, it has a idle problem were in park or neutral it idles up and down
VIDEO:
it has no check engine light, I have cleaned throttle body and sensors on it but it still does it,

note; it only happens at operating temperature, when its cold it idles at about 1500rpm and when its heated up it constantly goes up and down from 1500rpm to 1700rpm up and down , up and down

SOMEONE HELP!!

 

scan for pending codes
clean maf
check tps calibration
measure iacv coil resistance

 

mostly likely your iac there a phillips screw that u use to adjust the idle
spin to left: idle down
Spin to right: idle up
but u gotta disconnect the brown and gray connector to it when u do this
