ComancheKid45 Posted January 7, 2008 Share Posted January 7, 2008 My Truck has begun to act up again, i don't have enough time to type a report at the moment but I'm pretty sure its a TPS problem again, i had the thorttle body apart and cleaned it this weekend.....for now though what are some tell tale signs of a TPS issue? Truck is an 88 4.0 Automatic Thanks Link to comment Share on other sites More sharing options...
dfreeman616 Posted January 8, 2008 Share Posted January 8, 2008 erratic shifting is the primary issue, but that can also be caused by other issues. do you know how to test it with an analog ohm meter? Link to comment Share on other sites More sharing options...
