I just had a H22A swapped in, in placed of a H22A. After I test drive care ran fine, and no signs of trouble. Once I got on the road again I got a check engine light. So I drove it back to the shop and they checked the code and it said there was a misfire in cylinder 1. The car was driving fine. We reset the ECU and I went on my marry way. I even tried to get it inspected but the ECU said it was not finished cycling. As soon as I lefted the inspection station, I got a check engine light again. The car is driving fine.
