Brenton Posted November 24, 2010 Share Posted November 24, 2010 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: Quote Link to comment Share on other sites More sharing options...

Brenton Posted November 24, 2010 Author Share Posted November 24, 2010 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: Quote Link to comment Share on other sites More sharing options...
Brenton Posted December 29, 2010 Author Share Posted December 29, 2010 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. :cheers: Quote Link to comment Share on other sites More sharing options...
