I have a 2000 Yukon with the check engine light on.
Here's what's odd...
I just had it inspected and had no problems
I took it back to the inspection place and they said there were no codes and
that everything appeared correct. Then the light went off.
After a week of the light functioning EXACTLY as it should, it has come back
Does anyone have any idea what could be causing this? Is it a short? No
codes means nothing can be identified as a problem.
