Yep.
That means the engine isn't picking up faults so your problem
is either in the intake, ignition, or exhaust.
Given the milage you claim on the cat, dollars-to-donuts it is
plugged. A new one should cost about 100$ from any local muffler shop.
Aftermarket cats are good for about 80k-100k miles

Re: 93' Grand Cherokee Runs Rich? Codes
Thanks Doug. That makes sense. I'll have the cat checked out today.
I also just remembered, I put a can of STP gas additive in the tank of gas
currently running through. I wonder if it may have stirred some gunk up. The
old girl seems to be running better as it works through. I normally don't
like to use that stuff, but it was free with 5 qts. of Castrol. Been rolling
around in the rear footwell for a few weeks and I just happened to see it
and use it the last fillup.

STP is good. The best (my opinion) out there is the Chevron Techron
fuel system cleaner. Make sure the bottle says to use only every 3000
miles. The daily tank ones are too weak. Although I do use one from
NOS that contains a fuel drier for those times I pick up a tank of
slurry.
The other thing (I forget, too many messages, too small a brain)
have you replaced the fuel filter?

Re: 93' Grand Cherokee Runs Rich? Codes
Hi Doug,
It did cross my mind to change the fuel filter. Going to do that tomorrow.
After all these miles (258K) I'm only on the second filter.
Thanks for all the help.
BTW, the old girl's been working pretty good the past two days.
