scan tool for Renix......https://www.ebay.com/itm/Snap-on-mt2...edirect=mobile
I got on of the scanners, SnapOn MT2000 found me all sorts of problems on my xj
also run an intake vacuum test for engine health.
my Renix had a huge problem, becuase the egr valve seat broke so that egr was always on this caused a horroble mixture do to poor engine vacuum.

So far
Grounds are good. Skipped 2 for now being a 90. Got into the connectors and found that the relay on the driver side by the wipers look fried in the bottom. So I cleaned it up as much as possible and made sure wires weren’t melted together. And I pulled the coil and noted the icm connection points were blue so I took it out and cleaned it and reinstalled. About to go on a test drive and see what progress has been made.

Results
Ran great with a lower idle. But still sputtered and stumbled on acceleration. I will continue checking connectors and move down the list. Thank you.
this is the connector I found earlier

Thank you
I apologize I am slower these days. I haven’t made it through the first five steps yet. I was curious about timing because when I initially purchased this Jeep it barely made it home. I installed the cloyes double roller set up and installed it exactly the way I removed the previous one. I’m afraid it was initially on the wrong tooth. The Jeep is running great now after the few steps I have completed, but it sputters and stumbles when I accelerate. I apologize in advance, my head injury increases my challenges. Thank you for your time and your help. Truly appreciated.

Will cleaning the icm suffice, or should I replace it? I found one for $36 on rock auto. And I apologize to back pedal on you, but by chance do you know what your timing says when you put a light on it? I want to make sure I’m not off by a tooth.
like usual thank you in advance. You are kind to do this for everyone.

About 12* timing.
What's most important is the indexing. Tip 13.
I might clean the ICM. They rarely fail.
