Has anyone replaced their Powertrain Control Module (PCM) on their Jeep?

I have a 1995 Cherokee Sport with the 4.0 HO/auto. It idles horribly and "bucks" going down the road at speed. I have checked /replaced the following: plugs, wires, dizzy cap & rotor, CPS, TPS, MAP sensor, fuel pump and injectors. After eliminating these as issues, the only thing I can think of is the PCM.

If anyone has had experience with this or knows where I can get a good deal on a remanufactured PCM let me know. Any information would be helpful. Thanks in advance. :)

Did you replace the fuel filter ? Too bad I didn't know that you wanted a PCM since we were down in Moab over the weekend and I had my spare PCM in my jeep that you could have tried as an experiment.

Could be your MASS air flow sensor, but i would actually test stuff with a volt meter and find out if the PCM is bad or not. Throwing parts at a vechile is really stupid and expensive diagnos it and you will save alot of money
