Jeep wont inc. in rpms when i hit 4th

It will drive fine up until 4th gear then I push on the gas and no matter how much I push the accelerator my rpms stay the same no power :\ also I don't have to push down my brakes as much to brake what could that be?

Just as a guess... Im going to say a stuck caliper on the front.. drive for a while and then touch the wheel.... if its too hot to touch... then you have found the issue. Probably both issues actually

Does it kind of bog down a bit? Might be fuel filter.

the fact that changing the filter cured the problem momentarily, my guess is that you've got some sort of crud (rust maybe?) in the tank and now your filter is clogging up again.

run the tank as close to empty as you can and drop it down, pull the sender and inspect the inside. might be (over) due for a good flushing out, or maybe even replacing (20 gal poly )

Good luck

If you are not in an emissions test state then not only yes but hell yes. The nutter along with a hei setup or the team rush mod would make an unbelievable performance difference.
