2005 Jeep TJ Huge PROBLEMS

A few weeks ago my jeep ended up burning out the clutch do to being stuck in the snow on the so far coldest day of the year. The driver did not know how to put it in 4x4. Sadly this episode also took out the catalytic convertors. Maybe they were starting to go but they melted and were toast as well as being completely clogged. The jeep was left by the side of the road at this time the driver could not get the TJ in gear. When I went to start it sadly no start. Towed to the mechanic. Turned out the ignition module has gone bad so that was why not starting.... So I have replaced the cats the clutch and the module still NOT RUNNING WELL it is stumbling running poorly. It starts but does not have any power at all. I cannot really drive it like this.

Any ideas!!!!


Sadly the mechanics and myself are out of ideas.

Wow. The only suggestion I can give you is to not let your friends drive your Jeep.

Did the rig overheat during this episode? I mean, since they burnt out the clutch and melted the Cats is it possible they blew yer head gasket (small breach) and the coolant is causing the stumbling and loss of power? It isn't too far fetched running it that hard with no added airflow from the motion of the vehicle to assist in cooling. Any excessive smoke when running?

Just looking for more clues.

I know when I had to replace my cats I had to do the 02 sensors too, is it throwing any codes?

No issues with the coolant looks good still. The oil is good as well....

I had assumed you replaced the O2 sensors when you replaced the Cats, since the Cats were cooked. They will definitely cause your stumbling and low power issue if they aren't functioning properly.

Sounds like they should not be driving a manual if they couldn't figure out how to pull the tcase lever.

Any codes?

Did you just replace the 2 upper cats? There's a 3rd one downstream. If the upper 2 broke up, they have be clogging the downstream one. Or, it may have melted, too. That would explain no pwr.

Can we assume you're no longer dating? I dated this chick who couldn't drive in the snow, when she kept asking to borrow my Jeep, I kept answering that I would help her find a Jeep of her own. She ended up buying a Jeep but thankfully we broke it off, she was a gold-digger and I didn't have any gold left, LOL.

You may want to check some of the sensors, if the CAT burned up, it likely effected the accuracy or also burned up the O2 sensor at the least.

What is the ignition module that was replaced? The coil, PCM, or?

I believe it was more of the coil pack that was replaced So far they have managed to replace the Cats, Clutch and the Coil... I believe the coil part was around $200 or so...

Did they replace all 3 cats, or just the upper 2 by the engine?

Ignition is controlled by the computer which fires the coils. Crank sensor tells the computer when to fire them. If the crank sensor is bad, it usually won't run at all.

If you disconnect the exhaust pipe up by the engine and it runs fine, your exhaust is plugged further back.

Is the check engine light on?

All 3 cats were replaced with a new factory piece. The jeep starts fine it just has no power at all and you have to keep revving it to keep it running or it just stalls out.

They do a compression check?

Possibly burnt valves?
