Today at work, my truck started having some sort of issue (06 F-350), which caused a sort of "kick" and I'm not sure where to begin looking. While idling, it would begin "kicking" for a short period and then stop. The sensation from within the cab felt like someone closing the tailgate or lurching it from the back. Anyways, as I was leaving, I had a check engine light come one (static). I'm taking it to the shop in the morning and was hoping maybe someone could give me a lead in regards to what kind of damage I'm looking at.
