I recently replaced fuel pump and fuel filter and my jeep runs great but after a while of driving when I press the throttle to go faster it doesn't wanna do anything but choke itself out, any help?

 

I would run a test on the TPS when it is cold and when it is hot. There could be some heat related tolerance issues that are causing it to bog down. I would also clean the throttle body wile you are in there.

 

I cleaned the whole throttle body, all of the sensors with the correct cleaners and also replaced the TPS and how do you run a test on the TPS? thank you though i appreciate the feedback

 

Check out this thread, particularly post #11.

ok thank you very much

 

Is this on a Jeep Cherokee?
if so what year?
What's the fuel pressure in psi?
Did it run correctly before you changed these parts?

 

1996 jeep Cherokee 4.0 ho and I replaced the fuel pump and fuel filter and the pressures are where they need to be. it runs good idles well, just after a while of driving the throttle goes down but doesn't put anything to the wheels it just stalls itself out so I let off the gas and slightly push the throttle to keep myself going

 

I see that you replaced the TPS. did you use a Mopar one or another one. The Mopar TPS's are usually the way to go.

 

it is a bwd brand I'll try to get my hands on a mopar thanks for replying

 

So you tested the TPS & found it to be defective?
