02 Duramax 6.6 no power
Need advice on no power issue please. A buddy changed his fuel filter and after he changed the filter it would die on him/losing prime. I rebuilt the filter head for him. Started and ran fine except had no power. If I held the gas pedal steady the rpms would fluctuate. Took the MAP Sensor out and sitting in driveway it had all the power in the world with sensor out. Sensor was melted in metal tube. Replaced MAP with new one today. Now it won't hardly run at all.
