Good luck with this! A friend at work had an '05 Cobalt that kept throwing a cylinder #3 misfire code. After taking it to the Chevy Dealer and a few private garages nobody could fix it. When the car was coming due for inspection he traded it in! You might try reflashing the PCM with updated software. HTH. -Jim
