engine light
I am borrowing a friends f-350 and today while driving home the engine light came on. It seems to be running fine but i am not sure if this is a big problem or not.The truck seems to be working fine. I was driving home and it was snowing heavily on the way home and the truck was in 4wd. I also put about 6 gallon of diesel in it about 30 minutes before this happened. Please help.
