Well I went out and ran some more errands and she was running flawlessly.
I thought it was running pretty smooth. Before this problem cropped up, but it is even running smoother Now.
It may be my imagination but it seems like I am maintaining the same speed with less pedal now.

Uni: When you were talking about taking off that bracket to install the coil, I was thinking I should take all that crap off and clean that stuff, but I didn't

Good deal she's running flawlessly now, HD!

Yeah, I went the difficult route in removing the whole coil bracket but it needed it. It had never been off in 16 years and I had to put vise gripes on the wire connector blades/eyelets since seized, wrench on the bolt, with crap falling in my face.

Ticks me off to no end the dealer didn't check/clean the engine/PCM grounds when they installed the reman PCM 1 1/2 years ago. I'm sure that's what caused it to fail in the 1st place and why I had to install a 2nd one. Probably made my CKP fail twice too since it's grounded through the PCM. It's a vicious circle when it comes to these ground cables if they aren't clean/making good contact.

And if you ever have your alternator off again you may want to remove the mounting bracket and clean the where it connects to the engine block too. I couldn't believe how glazed/varnished it was since aluminum and steel/cast don't like each other.

All new/reman alternators now have a warning you better have a good ground wire attached. While maybe not necessary I made/ran a new ground wire from the right/bottom ground on the alternator to the front stud on the coil bracket just to be safe.

Also glad to see you washed it down and that dielectric grease should prevent some of the rust/corrosion in the future.

There should be a sticky on free stuff to do when your Jeep stalls. Mine had had at least 4 different stalls that were not related to the PCM or sensors that I fixed for about an hour labor. The next thing would be getting people to read the sticky.

That's a good idea, and if they weren't reading it, at least we could send them to it.

Please keep in mind here, that it is check and clean all your major connections and that doesn't mean just the grounds .

#1 Start with the battery .

There really aren't all that many and you can do them all in a hour or so and it cost you nothing unless you bust your knuckles .

Yes, it needs a Sticky and as I have said it here before many times .

" I have seen more Jeeps electrical problems fixed by cleaning the connections than by throwing new parts at it "

Not a perfect quote but close enough .

I'm having a similar issue. Can someone list all the various grounds or sensors I need to be cleaning? I'll look up location in the Haynes manual.

I'm working on a post to cover all the free easy stuff. Will take a few nights to get it all covered.

Cherokee, the grounds are on side of the block and on the fender by the battery. Normally cleaning a sensor wont help. You can clean IAC for idle problems

That's Great !!! Glad to see you are doing that, kudos to you, for putting in the time and effort to do it.
My ZJ ,has been starting and running fine since cleaning connections, and all my skin grew back from the wire wheel that jumped onto the back of my hand
