Check engine light


I have an 89 F350 SD 460. Over the past week, when I drive over rough stuff, the check engine light comes on. If I turn the truck off and restart it, it goes away.

I doesn't come on during normal driving.

Brian, It sounds like you may have a loose connection to one of your sensers or maybe a short. The next time it happens try going to auto zone and have them run the codes. This might give you an idea where the short or problem is. Hope this helps.
