It was lightly raining outside and I had to hit it because I pulled out in front of someone. I didnt peel out. But when I hit it I noticed my light came on. I turned the truck off quick and then turned it back on. It went away. Anyone know why it came on. Thanks.

 

You probably went faster than the speed sensor could read by spinning the wheels and it through a code. Wouldn't worry about it unless it comes back soon.

 

took it in today and i was running on 7 cylinders. The 4th one's coil was bad. Boy can You can tell a difference.
