Hey guys I have a mustang that only has 24000 miles. Rarely driven because of work vehicle. I just had it smog yesterday and prior to smogging the car I used a code reader with I/M to check to see if it will pass and it did. The smog station said that my check engine light is on. I told them right before I have them check at the parking lot, I checked it and it was good. Is it possible that the smog guy did something to my car to make it fail? He kept turning my car on and off plus he had a difficult time driving a stick. He must have start it at least 6 times. He wasn't enthusiastic either when I told them I had a coupon for smog test.
After that I reset the car and drove it for 3 days with varying speed... no issues at all.
