Hello Klaus. I was hoping you would weigh in. I pulled the codes three separate times to be sure and the codes were: 121 - Mass Air Flow sensor signal, 232 - Long Term Fuel Trim - Idling, and 231 - Long Term Fuel Trim - partial load. I am not sure exactly what they mean. The MAF sensor looks like a junk yard replacement part that someone put on the car before I got it. It has those marker numbers that u-pull-it yards use. I am thinking that possibly I may need the oxy sensors also. Just a guess. Perhaps the MAF is the main culprit and I affecting the oxy sensors? Someone else said to test the coil. Also I am not sure I understood how to get the service light off as per your instructions. Thanks for any help!!! -- john
