there's only a paper spacer on the end that the flex plate will scrape off during operation.

I am guessing that paper spacer is what I've heard not to remove prior to install?

I've also read about hooking up a scan tool to "re learn" the idle after replacing the CPS, I got the part from Jeep. Haven't had time to install yet, but will this afternoon. But is a scan tool required or is this "relearn" applicable in my situation?

Well, new sensor is in. ended up buying an 18 inch 3/8 extension to assist, bolt went out easy but sensor itself was a pita. Anyway, I've got the jeep up to temp, have driven around and seems like she's running a bit better. This is only day one, I'll continue to update this thread in case of anything relating to the symptoms occurs again.

a BIG thank you to this forum community for sharing experience and knowledge. I could not have gotten this far in the repair without you all!

A new cps will come with the spacer attached but if its not an OE Mopar cps I would NOT trust it. The correct spacing should be 0.032. I used a small piece of cardboard and superglued it to the cps. Check the thickness of the cardboard first with calipers or a micrometer. Genuine MOPAR is the way to go with ALL sensors.

Yup, Mopar sensor is what I installed. We're now a whole 7 days with no stalling.

Jeep still running good? I have had a lot of the same issues with mine. Replaced with a bs parts store match CPS to get it to start months back before I knew better and have been chasing the problem of the misfire at operating temp sense. What was yours doing before it stalled? Was it misfiring and giving it throttle would only make it worse? Hope your jeep is still running good, conquering the problem is a great feeling.

Just to piggy back on your post...

I've been having the exact same problem with my fiancee's 98 GC 4.0L. Will fire right up, and then out of the blue, usually either slowing for a light/stop sign or taking off from said light/stop sign, it will just die like someone turned the key off. We've tried numerous things: CamPS, coil, battery cables/terminals, cleaning terminals on computer, IAC, and the TPS so the CrankPS is my next part.

I'd like to know if you've had any other problems. Thanks

As an Update for everyone, My baby has been stall free since the replacement of my CrankPS, I did end up buying an 18" ratchet extension to make the job super easy. Now I just gotta find some info on how best to diagnose/find where all my oil leaks are coming from, I keep her topped off, but she drools like a mofo

For the record I believe a cereal box cardboard { I was told the boxtop} is the correct thickness to use as a spacer.
