Thread: idle issues

if it was a vacuum leak, wouldnt it act up all the time? this is an intermittent problem. sometimes when the car is accelerating, the car will sputter and wont take any more throttle. sometimes when you are decellerating it stalls. sometimes when its idling in gear the rpm will fluctuate from about 700-1500 rpm, and it doesnt set a code. help please!

hello again . just started the car and it set a trouble code, p0102, mass or volume air flow circuit low input.
does this mean i am looking at buying a new mass airflow sensor?where should i get it?thanks, jim
