Can anyone help with some advice? 04 Sierra c1500. Truck is showing incomplete for the EVAP monitor test when trying to pass emmissions. No engine light or anything showing any other fault.
I have been told to drive it to try to reset monitor and that has not worked. Gas tank is about 1/2 full, but it starting to feel 1/2 empty(LOL). Local dealer service looked at and could not find anything. Any ideas or experiences?
Thanks!
