i just bought my 05 Cobalt LS andi had to take it into the shop already because the Traction Control light and ABS lightwill sometimes stay on when i startthe car or they will turn on when i put the car in Reverse. so the shop replaced theElectronic Brake Control Module and that didnt solve the problem.i have never dealt with this before so i have no clue. Any ideas?

and i have been thinking about switching tofull synthetic ora blend?...i ranfull in my 00 grand cherokee before andlovedit but is it worth it for this car??
