check engine light. all commets are needed
i was doing some towing today, and i was reving my truck a little more than usual, up to 3 and a half grand. i was jerking the truck a little more than usual and it was pretty cold out. i was wondering if under these rough driving conditions, that a check engine light would come on. i also have many fog lights and strobe lights for towing purposes that were on and off all night. if anyone could help me out with comments or ideas i would appreciate it. i'm going down to autozone tomorrow to get the code but i was wondering if i could get some help to figure things out just in case they couldn't figure it out. the light came on after bout 5 hours of driving and idling,
