Jeep Wrangler Engine Troubles

I own a 2000 TJ 2.5L 5sp. I recently did a little mud bogging and found some problems afterward. The next time I turned it on, it idled at 1500 rpm. Later, on the highway, the check engine light went on and if I pressed more than half throttle, the engine would stutter badly. After a time, the idle returned to normal, the stuttering stayed, and power delivery from a standstill is rough.
Can anyone help with a diagnosis or solution?
thanks alot, Joe

Second, you may have got water in and around the coil rail which is now shorting out. If so you need to remove it, then thoroughly clean and dry both it, and the exposed heads of the spark plugs.
Before you do anything else though, check for codes which will point you in the right direction.
I have a 2.5L also. It'll be easy to swap, but you need to take off your air tube first to get easier access.

mac24, I do not think that my jeep is equipped with a coil rail, as there is a distributor cap with wires that connect directly to the spark plugs. Should I replace the wires or plugs or just dry them out?
Thank you!

The P1686 code relates to the SKIM it is an added option.
Does anyone know if a DRB III unit can reprogram the PCM for SKIM does not exist? Are there any aftermarket ODB units that can do the same type of programming? Are there any other options to get around this error condition?
No, unfortunately it can't. All diagnostic paths eventually lead to 'Faulty SKIM - Replace' or 'Faulty PCM - Replace'.
While there are solutions for other vehicle's PCMs, such as EFi Live, there's nothing I know of for the Wrangler; there's just not the market for it.
The most practical solution is to install a SKIM in the harness by the column, and tape a matching PassKey to it (or install a cylinder to match the key and use it as normal).
The lack of an airbag module will continue to throw a code but won't cause any drivability problems.
The reason I suggested adding a SKIM + key was that it might be easier and cheaper to find than a PCM. However, it would still have to be matched to the PCM with a DRBIII.
A new PCM is an option, as is one from a '97 before the SKIS was introduced.
The only problem with a '97 is that it's OBD system is unique to that year, kind of an OBD 1.5. :shades:
Shy of changing out my 1993 steering column how would I set up the module antenna and key to work together? I haven't seen the wiring diagram for the antenna. The wiring diagram that I have shows the module with connections to the data set ,ground, and PCM.
I may get a better idea of what I'm dealing with once I get into taking one out of a vehicle at an auto recyclers yard. I hope to get lucky and get a system supplied with two ignition keys. But, if you have an idea on compatibility that would be very helpful in my search.
Thanks for your time...and replies
I don't think the year of the SKIM matters but I'm not 100% sure of that.
Maybe another PCM (secondhand) would be easier if you can get one from a vehicle without SKIS as original equipment?
Today I was in ordering some other parts at my local Jeep dealership and I went over the story with the counter person. He said the dealer parts department uses the same place for PMC reprogramming.

Good find! It's funny that the dealer uses them too.
Speaks volumes for where Jeep is now at. :sick:
