a VERY good chance its ur throttle position sensor (sounds stupid i know) when the low trac light comes on the car also shifts at a high rpm no matter how little u push on the gas right (engine revs real high)

So what will that cost me to get fixed?

this will sound even more stupid....but I had this problem after doing a tune-up. There is a 2 wire plug connector in the tube that goes from throttle body to air cleaner...if its not plugged in...it will cause this reaction

intake air temperature sensor wont turn on a trac light and as for cost i have no clue the part was like 35 or 40 bucks and i put it in in my driveway. it wasnt on an ecotec engine though i was workin on the standard 2.2 on a car that was 2 yrs older than urs.
