A whole lotta questions in one post...

I can help with #3...

Disconnect the battery and leave it that way for a little while. This will cause the computer to reset. You will have to go through the "learning" process again (slightly rough idle for severl start-stop cycles).

As for the codes, call your local dealer and they can tell you what they mean - or I am sure someone here will have a service manual.

A couple weeks ago I took my car ('94 RT) to the drag strip. In my last race one of my plug wires came off and the check engine light came on. I stopped back in the pits and found the loose wire. I put it back on and the car ran fine with no obvious problems. The problem was that the check engine light came on during that last race. It now comes on and off occasionally even after normal driving. I don't think there is any damage, at least it doesn't act like it, the car seems to be running better than ever. But I did have the exhaust (muffler and cats) changed recently and used Nitrous a couple times. When I tested the trouble codes (with the three quick ignition flips) it came up with codes that someone told me meant the oxygen sensor was reading a rich or lean condition. So my questions are:

1. Could someone post or email me the trouble codes.
2. How are those codes read, it starts with a 1 - 2 and ends with a 1- 2 or something like that and the code is inbetween?
3. Is there a way to reset the computer? I'm thinking that while driving and having one cylinder not firing it would have sensed that the engine was running very rich because of all the fuel that wasn't getting burned in that cylinder. I think with putting the plug wire back on it is running right again but that the computer needs to be reset.
4. Any other advice on this?
