I got the service engine light and the wrench light on yesterday, I have a feeling that it is all tied in to the throttle control. I have 4,000 miles on my truck. I reset the computer but the lights still came back last night. My cruise control doesn't work thats why I think throttle control.

 

Well, that's what a warranty's for. s#*$ happens. You shouldn't however reset the computer without knowing what the specific code/problem is; that's what the dtc's and engine light are there for.

 

Take it to the dealer and they will probably re-program/re-flash the computer. I did and have had no more problems since.
