big problem:simple fix (truck bucking)

[mikediesel]

big problem only because it happened at the inspection station every time they would try to do the emissions test it would act up so they couldn't finish the test and the truck would fail. Finally after a week of trouble shooting and reading what everyone else has tried here on the site meaning fuel pumps, filters, wires, round wires ect. ect.
I found the throttle position sensor (tps) set screw was loose and it would move just enough to confuse the computer and start the truck bucking
Also there was no one thing that set it off sometimes I could run out for something and it wouldn’t happen at all other times as soon as I left the house it was time to saddle up also it wasn’t always bucking sometimes it would buck then feel like I was bragging an anchor any way I hope this helps someone else it drove me nuts this last week
