P0102 Pontiac is less likely a vacuum leak than a MAF problem. Mass Air Flow sensor. Measures amount of air entering intake. Faulty, dirty unplugged, or bad connection.( Circuit Low Input) http://www.obd-codes.com/p0102 and http://repairpal.com/obd-ii-code-p0102 agree, code is thrown when excessively low voltage from the sensor is sent to ECU. Would have to be a massive vacuum leak, your idle would be very high, so bad a leak more air is entering intake than passing through MAF


Try unplugging MAF with engine running..careful..no sleeves on.. see if it runs same. And a very very dirty air filter will also cause this


I cleaned my maf already and it looked fine but ill try the unplugging it while engine is running.

Yep, I'm NOT saying a vacuum leak is out of the question. Just odds
