jp2611 Have had this issue 3 times (my fault TJs don't need premium fuel) anyway I replaced with a "high flow" weld in Cat as was suggested. My brand is flowmaster. And to quote the mechanic, "that woke the ole' girl up"!

Green Bay TJ My 2000 TJ needed new cat last year. cost me $1600. OEM support was no longer available, Jeep sold in Maryland was under CARC emissions, so they ended up going with a 3rd party out of CA to get the cat + 2 mini cats. Hope yours costs less.

Kate The first thought that came to my mind was that someone had put a governor on it.

DuruConsigliere Just be aware that by putting it off you may cause other issues. Last time I had this problem a machanic told me that it could possibly mess up the valves. I've never experianced this myself as I had the money to fix it right away, but just to pass the info on to you. Something to do with the backpressure change in the exhaust system. Anyway, be aware that it could be a issue ok..

Jerry Bransford X2 on the guess being it's probably the cat. They can get so clogged/plugged up that the engine's exhaust gasses just can't make it out which is what causes the engine to bog down.

Nearly any muffler shop can do a quick pressure test on the cat to see if it is clogged or not.

Yeah check the cat. I just had mine replaced under the federal emissions warranty. They are 900$ otherwise since its 3 cats put together.

tkagad Ah, alright. I should probably get it repaired very soon then...

Thanks!!!
03-06-2012 11:29 AM
hambubba It'll bog your engine, but not sure at what speed. And it will probably get worse if it is the cat.
03-06-2012 11:22 AM
tkagad Do you think I can put off the repair for a week or so? Or is it likely to damage other components/get worse?
03-06-2012 11:05 AM
hambubba Been there, done that, on the highway, lol. Have a muffler shop check it out, basic WELD-IN replacement is fairly cheap. I haven't done anything at a shop in ages, I think mine was a little less than $200. But that was 10 years ago, lol.
03-06-2012 10:52 AM
tkagad You guys are good!

There IS a popping noise coming from the catalytic converter!

Thanks a lot!!!!
03-06-2012 09:01 AM
DuruConsigliere Agree with hambubba. When you get out of your jeep after running the highway put your ear down low and listen to it. If it sounds kind of like popcorn popping chances are the cone inside has cracked and might be clogging the exhaust.

tkagad I have stock gears and 31'' tires. I don't have anything heavy added to the jeep. It was perfectly fine before, even on the highway, but all of a sudden I'm having these issues.
03-06-2012 08:37 AM
denisbaldwin Sounds like a gearing issue. Do you have stock gears? Anything heavy added to your rig? What size tires?

Can't go past 60 mph....?

Hello,

I have an auto 04 rubi that seemed to work fine until recently, when I took it on the highway.

For some reason that I can't figure out, I can't go past 60 mph. I press the gas but my rpm's don't increase. They only increase when I press it down to the floor, in which case the rpm's jump up really high.

I'm guessing it's an issue with my transmission? At lower speeds it works perfectly fine.

Any help would be appreciated!
