I posted how to get your trouble code's to flash out check them with the key in the run position engine off.Trouble code's are the code's that are set when there is problem within your computer system in your car sensors etc.Let me know what code's you get and we can go from there.

You use a jumper wire between A & B terminals at datalink connector, key on, no crank. In that mode, the check engine lite starts flashing, you count the flashes to get the codes. Your looking for two digit codes. The code will relate to problem, hopefully. The datalink connector is on the lower edge of dash, driver side, I'll have to double check. Note below
