RE: Van for Sale; Runs Good
Okay, the catalytic converter on the 99 TJ is about spent. It obvious that I have exhaust restriction, and I've noticed increased exhaust fumes and underhood heat. I would prefer to just remove the thing, but I'm having some problems finding any info. The way I understand it, the second O2 sensor readings have no influence on fuel or ignition curves, and it's job is to simply verify that the cat is functioning. As far as I can gather, the only negative effect to removing it is that the check engine light will illuminate to warn you of a malfuntioning converter. Is this correct?
I would really like to know how to remove it without throwing the code. If the light is always illuminated, I wouldn't notice any other problems that it indicates.......so, what to do? Are there any devices on the market that will "fool" the computer into thinking the second O2 sensor is functioning properly, like there are for some other vehicles like Mustangs.
If the second O2 sensor really does just verify a difference in reading between itself and the front O2, what if I just remove the second sensor from the exhaust stream and leave it plugged in?
What do you guys think of the cheaper "high flow" converters? Does anyone know of a specific converter that is KNOWN to not throw codes in the Jeep with a high flow exhaust behind it?
