I was driving around in my 05 Expedition and all of a sudden it stalled I got a warning to check throttle positioning sensor I drove for a while and nothing happen until last week it was stalling more frequently an this time while I was driving 50 mph this was getting scary and taken longer to restart each time. So I researched it electronic throttle body and accelerator no throttle cable. I took it to the dealer what a racket they charged me a $100.00 for diagnostic which I had already gave them the code $36.00 for labor and $90.50 for the part. I could of done it myself but because it uses the EEC and other componets I decided to let the experts do their jobs.
Lets see it the potentiometer that is on the throttle body was the problem.
