The engine warning light came on this weekend. Had The local Mechanic plug in to give me the computer diagnostic and it came up P-0432???? I was told that is "Main Catalyst Efficiency Below Threshold - Bank 2"????? Can anyone give me an idea of my next move. Thanks ahead of time.

You can borrow Ryan's code reader, but in the long run, if you are going to own a TJ, you should buy one. For less than $20- you can get a basic one that gives you the codes; then use the site Mike gave you to determine what they really mean. Here's the reader that's always in my jeep: http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
