If you check it with an analog volt meter, you can see if it jumps around by slowly opening the throttle. There could be a bad winding in the tps and cause the voltage change to jump. There should be a smooth transition between the low voltage and the high voltage. Does the truck act up when you floor it, or just normal cruising?

I just had my 87 Ranger's 2.9v6 serviced at a local repair shop. They had a machine called a "MotorVac" that they hooked up to my fuel rail. This machine then injects a detergent/gas mix that cleans out carbon in the engine. It cleans carbon from everywhere your gas goes. It cost $100.00 and took three hours. I found out from my local Napa dealer who had sold this "MotorVac" system to the shop. Go to www.motorvac.com to read more.
