so i just had mass air flow changed from dave b so was genuine nissan part. i changed air filter as well at the same time. the car ran great for about a month then one day i notced it was idleing high while in gear, about 1 1/2 and you could feel it through the brakes.

no codes are being thrown and to stop it i just have to turn it off then back on at a stop light?

any ideas on what it could be? thanks to any one that can help. with gas prices so high, I don't want the idle being so high and it really seems to heat up my brakes. It is almost like i am driving with two feet which is not good for the car.

 

you haven't cleaned the TB have you?

 

Check for codes anyway, you might have one pending that hasn't occured enough to trigger an SES light.

 

Perform a idle relearn...

 

well thanks for the imput. ill let my mechanic know what you guys suggested
