It was brought to my attention that the images in this post vanished. This post was done in the early days of these boards when images could not be uploaded. They were links to an old server we no longer have. I was going to edit the original post and insert the new links so it would just be fixed but was not able to do that. So....here are the missing images reposted.

Hakim,

I would monitor the crank and cam signals along with ignition coil current and injection if you have the four channel scope. Anytime you have a Chrysler with disrupted ignition and/or injection, the cam and crank inputs are a suspect.
