Intermittent issues with service stabilitrak and service traction control. Both are currently showing on DIC and was 4-6 months ago when I last had this issue. Looking online, this seems to be common issue with no solution.
What is your question?
Before the messages came on DIC, I noticed engine seems to be derated. Almost feels like a brake dragging. The throttle position sensor has been replaced several Thousand miles ago. 155,270 miles on truck now. Have also had repeated issues with P0446- clean evap vent and that seems to be resolved.
