Your 92 has only 1 O2 sensor and that's on the down tube just after the exhaust manifold..There is no after cat O2 sensor..So you are all good..

JeepersCreepers

really! sweet. thank you for clearing that up. I hope now i will get alittle bit better gas mileage cause i think the o2 sensor that was on there before was original. lol.

cut it off

thats what i did on my 01 better mpg and its louder (and ya get like a 100 bucks at the scrap yard)

JeepersCreepers

100 bucks at the scrap yard? why so much.

kmanxj5050

there is platinum inside of them and xj's have a small import cat


we have people that steal them off of brand new cars at the dealer around here lol

JeepersCreepers

ya i heard that in the new where i live. people are having there cats cut off in parking lots.

JeepersCreepers

sweet. im cutting my cat off and i have an old exhaust system with a cat on it too so those 2 cats might pay for a new exhaust for my jeep. sweet.

Just a reminder that cats are required by federal law.,...not to mention not exactly environmentally friendly to not run one and also one more thing to add to the fire for those who want to take away public wheeling land..

JeepersCreepers

ohh. well i will just replace my cat with the magnaflow cat.

kmanxj5050

ok i see what you are saying but WHY??? what is the difference between joe blows 86 pioneer with a blown out cat!! and me not having one!!!!

Honestly someone running one that doesn't work is as bad as not having one at all..Mine still works just not overly well but the new one is due in this week then a complete new exhaust gets tossed on.. The increase in mpg isn't much so I don't see what the advantage is in not running one? My buddy wasn't running one for a while to test the mpg increase and it was not what I would call worth while..

AND (this was not mentioned) Removal ,without the intent of replacement, of any emissions component be it by a repair shop or by owner can result in a hefty fine (I last heard $10,000) and jail-time.

For a few bucks a new converter is worth it. You may not see any immediate improvement of MPG... that motors been running with a stuffed up exhaust for mostlikely a long time, it will take some time to get things back to running the way they are supposed to.
There is probably alot of carbon built up on the exhaust valves that they arent sealing and flowing the way they should.

I would suggest, change entire exhaust including O2 sensor and Converter. Run some Seafoam thru the intake. Clean off your IAT (or relocate). Unclog your CCV.

Woops....forgot we're talking OBD-I here, so there is only one o2 sensor.....my bad!

In that case, replace that one oxygen sensor then...waaaaaaay past due for replacement.

i dont run one because how am i gonna get caught with 10 cops in my town who wouldnt know one if they saw one lol and for a 100 bucks it was worth it

okcjeeper

So is it ok to rob a bank or shoot a person if ya won't get caught..?
