1999 GMC Sierra V8 Four Wheel Drive Automatic
I own a code reader and it threw out the code P0442! What things should I check to diagnose this? I know my gas cap is one thing, but what else would trigger that code? My check engine light is constantly on and when I try to reset it it comes right back on!
have the same problem?
