I replaced the Coolant temp sensor and went to the car wash and it still sputters and backfires until driven for awhile. I think something is getting wet that shouldnt be. It was washed with the hood down. It just doesnt make sense to me why washing the car would do this. I will find out either later tonight or tomorrow morning after the engine has completely cooled to see if the new sensor helps the cold start up and drive.
