shuts off what can be the problem? I ordered the part from ebay because Suzuki sells the part with the throttle body at the whopping price of 1,400. i payed 1,800 for the car. I cleaned all the wiring and changed MAF but the check engine light came out again. what other problems can it be? im so frustated bc i just bought the car 1 week ago. and the previous owner does'nt want to give me my money back.
