Loss of power

I have a 2002 Wrangler with 80,000 mls. I am the original owner. I have been trying to fix a 5 year old problem with accelerating up any incline. If the rpms drop below 2k I have to downshift to the next gear. I can push the pedal all the way to the floor with no response. Going down an incline is fine. Also it's all I can do to reach a speed over 70mph. Any thoughts.

What size motor do you have? Sounds to me like you have a 4 cylinder 2.4L. If that's the case then that's what your stuck with. Great for offloading but not so great for the highway. I had a 97 that top out at 78mph going down hill with the wind to my back.
If you have the 6cyl or bigger id start looking at the basics first; spark plugs/wires. Could be a fuel problem, check the fuel pump pressure.

It's a 6 cylinder 4.0. The thing is I drove it to Knoxville and could pass everything on the road. Took it to the dealer when I returned to have it serviced and that's when then trouble started.

Sorry. New to this.. I have taken it to most of the big shops and have had just about everything done to it. I'm helping the local economy..the last dealer wanted to replace the entire exhaust system. $2900. No thanks Someone mentioned just replace the cat.

A plugged up cat will cause a big loss of power while everything else seems OK.

Soooo. Would it be possible to damage a cat if the jeep were to fall off .... say a garage lift. Is there anything above the cat that could have flattened it. I beleive the dealer dropped the Jeep off the lift. No actual proof except for the bent front DS which caused a terrible vib at 65 mph and was told it was the tires. balanced and rotated umptine times with out any cure; and the dent in the oil pan and the broken transmission mount all which I found 4 yrs later. I only take it offroad on the sand. This is a very long story. this is some of the high lights
