"An inaccurate throttle-position-sensor signal to the vehicle's computer can cause poor engine performance and erratic engine and transmission operation. You may very well be dealing with a poor electrical connection at the throttle-position-sensor as opposed the the failure of the sensor itself. It's a somewhat common occurrence in automotive applications where an electrical component is replaced and the symptons disappear for a period of time, whereas the porblem was actually at the electrical connector and not the sensor. This occurs when the poor connection is disturbed enough during the replacement of the component that it temporarily reestablishes electrical contact, then corrosion and engine vibration will cuse the problem to return in a short period of time. The TPS connector has shown a significant amount of problems on '91 and '92 Diesel Rams, and Dodge has come out with an updated TPS Wiring Assembly Package (part # 4728883) to correct the condition. If the female terminals at the TPS connector are spreading or showing signs of corrosion, this package should take care of the problem. The installation will require rosin-core solder and heat-shrink tubing. "
