I installed a GM MAFT yesterday in my 90 TSi and when I hooked up my logger to start getting my fuel trims tuned I noticed that my O2 reading is coming in at 4.98V (after engine warm-up). Each of my fuel trims is at 100% because I reset my battery and at idle my O2 reading remains at 4.98V...
I need help to diagnose a strange wheel noise I've been experiencing in my '97 GS-T. The noise can best be described as sounding similar to a cricket chirping and it occurs more frequently as speed increases. The noise will cease when the brakes are applied but will occur again as the brake is...

This weekend I disconnected the airbag electrical connection from the back of the airbag unit on the steering wheel. After I reconnected and reassembled the steering wheel, the SRS warning light on the gauge display stayed on. I checked and rechecked the connections behind the airbag, nothing...
