During a short road trip earlier this weekend I experienced what I can only describe as a misfire or TC issue and I am trying to determine the culprit.
Some background: 22 CT5V BW A10 just over 26k miles.
How it happened: I was cruising at around 45mph and attempted to pass a slower vehicle which involved maybe half throttle to downshift and enter the other lane to get around said vehicle. When this occurred It felt like the car was cutting out but wheels were not spinning, no yaw movement or anything like that but I did get multiple lights and bells saying Service rear diff, stabilitrak error and then the check engine light along with an additional light that I have not noticed before. I wasn't in an area that I could stop so I continued on for about another mile and the lights extinguished and the car felt normal. No other issues.
Since that day: I tried to replicate the issue again and have noticed even with PTU in race 2 mode with TC off, and using paddles to shift, the car feels like it's not applying full power. I am guessing possible TC issue with a wheel speed sensor or possibly bad plug/wire. I would think I would have a CEL at this point though?
Fuel is good, oil level and pressure is good and oil samples all good. No noticeable coil issues. Is there a way I can troubleshoot more to eliminate the TC or sensor issue and isolate to just a plug/coil issue?
