I have a 96 Sub. In the past, the truck has occassionally thrown P0175 System Too Rich (Bank 2) and the Bank 1 version of the same code but with NO drivability symptoms.
Recently, it has been behaving badly. Occassionally cuts out at about 45 MPH at part throttle and sometimes stalls when coming to a stop or at idle. When it has stalled it throws a P0102 - Mass Air Flow (MAF) Circuit Low Input. I am not sure whether this is cause or effect.
Recently it threw both P0102 and P0175 after one of the "cutout" events at speed.
I have checked the MAF and cleaned it with MAF sensor cleaner. Checked all of the connections around the intake.
Is there a clue in the fact that i got both of them at the same time?
