help.

My 94 yj has manual transmission and has awsome power around town. When I get on interstate top speed is 55 mph and I have to downahift to keep up. The weird thing is that when I down shift to 4th gear the rpms still are below 2000. Any suggestions where I should start.

Welcome!
There are a few threads about this topic. I had the same problem and changed air filter, fuel filter, plugs/plug wires, and did the seafoam treatment. Then after driving 100 miles or so with seafoam in oil, changed all fluids. Now I can easily maintain 75 mph on highway in 5th gear. Some will argue that this doesn't work, but it definitely worked for me.

Because this is the newbie check-in area, you may not get the answers you are looking for. I suggest you check out this forum area and post your questions there, I think you'll get a better response.
