I have a 98 tj Jeep 2. 5lt with on it 57,000 now. What I experienced was a major power loss in the while getting on the freeway. The symptoms were as follows. The engine would rev up but the rpms & speed would rise slowly. I though maybe the clutch was slipping and pulled off the freeway and drove it back home . I noticed it got worse and the engine was running poorly at idle and if you gave it gas it would bog down and die. I also noticed strong exhaust fumes and very little pressure from the exhaust pipe. So I took it to the muffler shop for a new catalytic converter and they informed me that I should take it to the Jeep dealer. Because in CA there's a federal recall law that states that the dealer must replace the catalytic converter at no cost to the owner if it fails before 80,000 miles regardless if you bought it new or not and mine had 56,000. So I took it to the dealer and they installed a brand new catalytic converter free of charge and labor. The Jeeps runs great and the dealership was very nice . They said they have had problems on this with certain models. Hope this helps. Oh if you really want to know if that's the problem just disconnect the exhaust pipe going up to the exhaust manifold real quick and fire it up if it starts right up and has power then you know that's it. But hook it back up don't drive it like that. You might damage the engine. You'll need a 14mm deep socket and some wd40 to removed the 2 nuts on the studs. That's it.

The catalytic converter broke and the part from it clogged up , which caused the vehicle to loose power. The vehicle wouldn't exceed 50-60 mph along with rattling due to an internally broken converter. The interior door hinge was inoperative.

Terrible rattling noise coming from catalytic converter. Sounds like part or parts have shaken loose. No performance loss noticed yet, but very annoying.

There was a rattling noise in the front of vehicle. Took vehicle to dealer, and they stated that a piece of catalytic converter was floating around, and could block the exhaust. Driver stated vehicle stalled at 65 as a result. Consumer was almost hit by an 18 wheeler. Please provide any further information.

All three failures have taken place in the last three months. The latest being the catalytic converter. Have there been other failures reported.

I have only included the one date I can remember that Jeep was in the repair shop. But, to this date, after Jeep warms up and then is shut off for approx 20 minutes, it hesitates on acceleration. Dealer said couldnt duplicate problem. Oil gauge dropped to zero, then engine knocked & I shut off. Dealer said oil pressure ok, could not duplicate prob. It still drops below 20 sometimes, but not zero again. I have had manifold bolts replaced twice and catalytic converter replaced once. Water leaks on passenger side & drivers seat belt gets caught in door latch.

In the morning the vehicle would backfire andwhen the vehicle is driven after it sits for 20 minutes. Now the dealer has replaced a exhaust manifold /catalytic converter/tps sensor/air intake housing,a broken stud in the exhaust manifold to head assembly, this has been going on for the past year and I get the same reply I can't find the problem or it's in the computer. This was all taken care off, but the problem still exsists. I've talked ato a lawyer and he couldn't help me. Maybe you can as this does cause a flame to come out of the intake. And now it's getting worse now it's when I'm driving down the road a 25 - 30 mph. What can I do? please help, scared to drive it might explode the engine while I'm driving with my son or girlfriend.
