Two questions for a 2002 Duramax:
What are you guys seeing for boost at around 2000 rpm under load? We have an engine in a boat and have been seeing 38lbs (absolute measurement with 14.7 being at idle). Is this high? We seem to have fairly low exhaust gas temps.
Also, we have one trouble code that keeps coming up. The MAF sensor will run at around 38 to 40 gm/sec at idle and gradually rise with rpm (viewed using autoenginuity software). Sometimes at idle, the value will drop to a reading of 2.76 (always the same number) for a split second. This causes either DTC P0101 or DTC P0102 to set. Any thoughts?
