Strong possibility, with the mileage that's got to be on it, and
the filter, at least is clogged.

Re: Cherokee problem
I would just be cleaning the CPS plug and socket with a decent
electronic contact cleaner then seal it up with some dielectric grease
on the seal.
That plug is a trouble spot for sure.
I also would be cleaning the TPS connection on the throttle body, heck
any I could get my hands on while I was at it is how I go after that
kind of thing. The grease on the seals does the plug contacts wonders.

Ok.. 55 = end of codes.
That leaves two more areas to consider. Fuel and spark. A failing
coil will cause stammering, a plugged fuel filter will limit speed and
contaminated fuel will cause all sorts of bucking, especially if she
got a tank of water/crud. Neither fuel nor spark problems will set
codes in that model year.
Unless the fuel filter has been replaced recently I'd have her do
that too. easy job, just need a couple of rags to fend off the fuel
drips.
This isn't cheap (about 100-150) but it is very effective in
cleaning the fuel rail/injectors/valves/and on back.

Most shops can also do a leak and flow test on the injectors.
But try the filter first.
Coils are funky. While there is a resistance range I've found
that the resistance can be in spec and the coil still fubar.
This little gizmo works well and it's cheap. 10$ or so.
