I was driving home today and all of the sudden when I would take off from a stop you could floor it and it would barely go, it would get up to 55 but took a while. When I got home. I decided to shift over to manual and take it back out. It drove fine. I stopped and turned around and put it back in Drive and it ran fine for me the whole way back home. Any ideas why putting it manual for a brief time woul fix it. I was told a ong time a go about the fuel filter getting clogged under the rear seat, but it seems like it would do the same in manual. I also, searched and saw some thing about a TPS Sensor. If anyone has or knows the problem/solution please let me know. As I write this my old truck is in the shop getting $1000 worth of work done too it, that I do not have. LOL.
