I have a 92 v6 that over the last few weeks has gone from running good to barely idling. The engine is in a good state of tune. It started surging or bucking at about 40 mph and also had a little rough idle. Then in about two days it went from that to barely running. No codes were set, egr valve is ok, plugs, wires,dist cap new and check out ok. I searched here and found similar problems and they pointed to the tps. When I unplug this the engine runs fine. Is this easy to change? I did read roger browns site and sort of understand. I can get the part from napa for 147.00 . I just wonder if it is a simple install. I also need to know if I can drive the truck with the tps unhooked without problems. I need it for work. Sorry for the long post. Thanks Bill
