I have gotten the same code on my 97tj but have since had it cleared. I have been reading alot about this and see there are quite a few other jeeps with the same problem. Someone posted something about changing the whole distributor and that fixed the problem. I also has a mechanic tell me that it could be the timing chain. How that could be, I have no Idea. My light came on after downshifting to make it up a hill. Well, its been about 20o miles and I haven't gotten any CELs since. Could be something out of syn within distributor if I am understanding it right, beats me though. Here is what I found on google.
