Unhappy 94 YJ 2.5 L - No Power

When driving on the street and it requires going up a hill, it goes down to 35 MPH and I have to downshift. On a level road I can get up to 55 but not much more. I just passed emissions in GA. Is it the catalytic converter? I have 32 x 11.5's on it.....

Sorry, but like Countryboy said, that is the quirks of a 2.5 and larger tires. The easy fix is to re-gear. Not cheap, but gives more bang for the buck than go fast items like cold air intake or throttle body spacers etc.

If you are really unhappy with the performance, you may want to sell the 4 banger and replace it with a 4.0 6 cylinder. In my opinion, I say keep the Jeep you have, it looks like a nice one from your avatar and enjoy the fact you don't have to worry about speeding tickets.

My 4 cyl goes pretty fast on the down hills, To almost 70mph so I can make it on the up hills and only down shift to 4th and keep above 50mph. (I HAVE A 2" LIFT AND 30" TIRES.)

Mine did the same-- heres why..

mine is a 87 YJ and with 33's I could barely get above 65... I decided to change the gears after rebuilding the motor. It came stock with 4.11's- I chenged them to 4.56's.. I now get above 80 mph and can use 5th gear all the time on the highway. A little costly and I lost some low range power- but I am not rock crawling- so it does not bother me.
