heat.YJ im having the same problem once i lifted it. all my power was gone i put a new fuel filter in that helped a little bit but still can barely get up to 45 mph within in two miles so if you get something that works plz let me know

Jeeper_Kile Yeah all these could be it, idk why it would be so bad because i can drive 55mph no problem in my 4cyl in 4th and sometimes 5th pending on the road

Usually a clogged cat. Your's is probably over due to be replaced.

YJman Most 6 cylinders came with 3.07s in the diffs (for standard transmissions). My 92 is on 33s as well. I got lucky and have 3.55 gears. To help the power I put in a high flow catalytic converter and built my own free flowing air intake. And I just maintain it the best I can.

AKYJ If you are running 33s with stock gearing that's your problem you need 4:10s minimum To get your highway speed back.

banks316 55 mph in 4th sounds normal. I don't hit 5th till 65ish I'm running 4.56 gears with 36 13.5 swampers. Have you done a full tune up? New plugs, wires, cap, rotor, air filter, them filter? Are the plugs gapped right. They should be .035 Have you checked all the header bolts, exaust for leaks. What does the exaust smell like? If its smells like gas then it might be running rich. In that case new o2 sensor.

XJ Knight my vote is decide what your final tire size is gonna be then prepare for that.. Basically rear axle swap and then regear.. Someone said cloged cat coverter earlier as well.. that is a interesting thought

THEJAG5 yup. tried all the simple fixes...and my engine is still sluggish.

Hectic symptoms can be

Power loss, overheating, glowing header/manifold, whistling exhaust note, missing, marble sound in cat.

Idles fine but when you reach the upper rpm range with a load ,like going up a big hill or bridge it will really bog down.

bruceandjo95yj lol dam ya guess that would stink
i assume you have tried the easy stuff...plugs,plug wires and etc etc?
Could be that easy if you havent...
11-24-2011 07:35 PM
THEJAG5 sometimes, it barely goes 55mph in 4th gear!... im not asking that much from my jeep. i just wanna be able to go 55 in 5th gear.lol
11-24-2011 07:28 PM
bruceandjo95yj Keep in mind that its a older jeep and not a race car
Keep tellin the wife and relatives the same thing..
11-24-2011 07:26 PM
XJ Knight Catylitic converter.. and yeah guessing your on stock axle gearing so the 33's are slowing you down some
11-24-2011 07:15 PM
THEJAG5 "cat's" ?
and im running 33s on it.
11-24-2011 07:13 PM
XJ Knight If you got larger tires with stock gears then that could be your problem..
11-24-2011 07:10 PM
Hectic clogged cat's can cause loss of power.
