(A little information about 97 Yukon before diving into my issue. It had been parked for a while. I had to replace the battery and the fuel pump before putting it back on the road. I have drove it proper amount of miles so it could go through it's drive cycle for inspection.)
Took it to be inspected today and wouldn't pass because of no service engine light. I took it autozone to check for codes. It pulled up an 02 sensor code, but I was told that would cause the light to come on and have nothing to do with it not working. Took it to another shop following that. The mechanic checked it and said it had cycled for everything to pass inspection, but a bulb was probably causing it to show an error code for "MIL off." I have since replaced the bulb and that didn't help at all. I've searched online and not finding any help for dealing with a Yukon, so figured I would try here. Any help would be greatly appreciated!
