Nissan Repair: Starting My 01 Maxima, mass airflow sensor, air control valve


Question
When I start the car the rpm goes up to about 1 1/2 and then drops all the way down and shuts off. So in order to let it start i have to start it and hold the gas for about 2 seconds and then its fine. Any idea what might be causing this?

Answer
Kalo,

I assume there are no codes present.  If this is the case you need to check the idle air control valve and the throttle position switch.  If you had a badd mass airflow sensor it would idle badly all the time and possibly not even stay running due to a low idle.
