My 98 4.0 has something loose inside the Cat. It doesn't affect the performance but it sounds just like I have a broken exhaust pipe hanger. I have searched the web looking for an after market Cat but can't find one. The dealer wants $850.00. I don't want to go to a straight pipe. Anyone know of anyone who makes a California legal Cat? Any one in California have one to sell?
did you have the local dealer check it out? call them up and tell them that you believe your jeep has a recall : E22-PCM reprogramming and catalytic converter inspection
It appears the failures are only for 1996-1998 Chrysler vehicles (including Jeep Wrangler and Cherokee). It appears that both the cat and the PCM were recalled. The cat for falling apart and rattling and the PCM for not detecting a cat failure. I wasnt able to find anything showing the exact range of VINs this was for... but perhaps yours doesnt fall into that range.
From the first page of the recall

The Powertain Control Module (PCM) on about 467,400 of the above vehicles may not be capable of detecting a deteriorating catalytic converter. Also, under certain conditions, some catalytic converters may be subject to mechanical degradation that causes a rattle.
it's illegal in most if not all states, but no one said to install one from another vehicle.
Yeah, but if I could find a used one I'd install it. My cat's shot and I just lost my job. So, the genius lawmakers are going to have me driving on a bad cat, instead of a good condition used cat until I can afford to replace it.
When my time comes, mix my ashes with gunpowder encased in brass, point me towards murderer's and pedophile's and let me fly.
Yea George, I spoke with Plaza and they said they can weld in a universal Cat. The problem is I keep my Jeep at my house in Borrego Springs so I was hoping for a direct fit and install it myself. I may bring it home during the summer (when it's as hot as the surface of the sun there) and have them do it. Thanks for the help, PM me if you are going to be in B.S. Great wheelin there.
I used to do a lot of wheeling there years ago. We used to go out by the old landing strip. My friends father lives in B.S. His last name is Partridge. You've probably seen his Kawasaki green class 5/16 baja with a built acura eng in it. It's kind of street legal.
I will definately PM you when I go out there again. It's been about 10 yrs.
