Re: 96 XJ Hesitation when hot & cant rev

I would wonder if someone gutted the cat thinking they had an issue with a plugged cat. I cannot imagine how a hollowed out cat would cause this problem. However, if the guts of the cat wound up in the muffler I can see how that could relate.

However, I would be more inclined to think that you are having an electrical issue of some form. I could easily see it being a sensor or a coil. Something is probably increasing in resistance when hot.

You probably need access to a scanner that can show you readings for each sensor. Compare readings cold to readings hot. See if something is changing that should not be. I am not sure how you test a coil, but see if you can find differences between hot and cold for the coil.
