2002 Chevy Tahoe V8 Four Wheel Drive Automatic 136000 miles
Service Engine Light came on last night - same time as the clock on the radio reset to 12:00. Radio pre-sets did not change.
Engine is running fine and no other accessories or lights seem to be affected.
Took it to Auozone to pull the ODBII code, but there was no power to the connection plug under the dash.
Guy said it might be a fuse problem keeping the plug from relaying the trouble code, but I can't find a fuse for the PCM anywhere! What would cause the plug to be unpowered but not make the engine run rough?
have the same problem?
