2003 GMC Safari Q&A
2003 GMC Safari Question: Engine started jerking intermittently and Check Engine Light went on.
P0102 also relates to the MAF sensor - frequency less than 1200 Hz. I'm wondering - when you replaced the MAF sensor, did you replace the MAF wiring connector? Sometimes the connector can have an open circuit. And - the processor's memory should be cleared after replacing this sensor. Last - check for any air leaks from the air box or air tube. - DaveJHM
