Warm up and lose power....

[Brenton]

I've got an issue that I want to know if anybody is familiar with. Even after sitting a little while, my Comanche is very good about starting....its not very cold natured. Let it idle a few minutes, take off, and it runs great...but drive around town for awhile, and it loses its "uumph". :???: It will still go, but only has throttle response to a certain point. I can floor it and nothing changes....it won't maintain slight inclines, it just kinda wimps out. Any thoughts would be great. Thanks. :thumbsup:

That was a thought of mine too....got the new filter, just got to replace old one and see what it does...

vacuum issue?

Yeah, that could definitely be an issue....all those little lines and hoses are a mess. Previous owner did some top notch "repairs" :roll:

Alright, it seems all these symptoms were because of a failing fuel pump. Before I could change the fuel filter, the truck crapped out and wouldn't start...changed the pump, it was good to go. I also changed the filter and cleaned the tank while I was at it. Thanks for the help.
