This was a pretty common thing on these older Chrysler vehicles. The PCM gets a loose solder joint and it causes this issue. The telltale is tapping the PCM. We need to replace this and then retest all the other issues however, I am sure this will fix them.
I attached the process. You need to program the PCM after replacement unless you find one that the company programs it for you prior to sending it.
Let us know what questions you have. Thanks
