Hi,
I'm a new diesel owner of a 97 1500 Z71. I recently had it in the shop to have my lifter pump and IP replaced under warranty. When I left the shop the MIL light came on with a code indicating Mass AirFlow Sensor. I cleaned the sensor , verfied filter and any obstrcutions. Reset the MIL light and drove for another 350km before the code appeared. Cleared the code again and drove another 100km before it appeared. I completely inplugged the sensor and it took 40km before the MIL went on and showed the same code. Frustrated I sent the truck back to the dealer who did the original work suspecting that they most likely screwed something up when they replaced the IP. They have yet to reproduce the problem or find anything wrong. Has this problem happened to anyone else?
