Question about 1991 Jeep Wrangler
Posted by Anonymous on
If its using a lot more fuel than usual its almost garaunteed an 02 Sensor. Those are located on the Exhaust Manifold's, are about the size of your thumb, and generally have 2, or 3 wires coming from them. If you can, check them for operation before you replace them as sometimes they're kindof expensive.

Clogged Catalytic Converter. What happens is as you push down harder on the accelerator you force more gas into the system causing a slightly richer mixture and more exhaust flow is neccessary. The easiest way to look for a clogged cat is when it's dark out take it for a ride causing it perform it's problem look under the vehicle if the cat is literally glowing red hot you either have a clogged cat or an extremely rich fuel mixture.

Aaron, I had the same problem. It is the most expensive part of course the computer. I replaced everything as well till I replaced it. They are remanufactured and have had problems with them as well. I am on my third one now at 200k miles. Oh and by the way it does not show up on the diagnostic check. Good luck
