I took my truck to the local car wash for a clean up and when I started the truck the check engine light was on. Seems to be running fine though with no missing or rough idle.

NOTE- Its one of those auto washes that the attendant drives the truck on the track then gets out and it gets pulled through.

Did u have the code run? Most auto parts stores will do it for free.

Going to have it run tomorrow if the light is still on. I was thinking maybe something got wet and caused it to come on so I was going to wait overnight and see if it was still on before I ran the code.
