Ok last night after driving in the snow storm I got the dreaded engine power is reduced and service stabilitrack warning. Watched some videos and took throttle body off and cleaned it. Drove fine for 10 minutes then it came back on and I limped home like a 1 legged elephant . I don't want to end up being in a revolving door at the service station waiting for them to hit and miss on this till they figure it out while my service charges skyrocket. What does anyone suggest to try next
