Searched for information on Mass Air Sensor on the LB7 Duramax. Lots of information but the issue I am experiencing is not covered. Hope the brain trust here can help me out.
My 2002 is totally stock and is throwing the P0101 code. I replaced the air filter. When the code is on the truck runs well. A few seconds after clearing the code the truck smokes heavily. The smoke clears with a few hits on the throttle and runs normally. Within a few miles the code returns.
Replacing the Mass Air Flow sensor changed nothing. Could find no air leaks, cables look good.
All comments appreciated.
