Well I was at the gas station tonight to put gas in my car after clearing the PCM codes in my car for a stupid o2 sensor problem!!! arggggggg anyway I shut the car off put some gas in the caddy and got back in. Now this is the weird part. I turned on the car and it said "ice possible" what the hell? i know what that means but why did it show up? it was only 36 degrees outside. Someone fill me in?
