Fired it up again and the misfire moved to #4. Currently Checking power and ground to ecm. Could the over charging issue hurt anything else?

Those ECM’s are very glitchy. Doesn’t take much to smoke one especially the older Celect’s, flashing one there is a 50% chance it will die. The Celect+ is slightly more forgiving but air in the system will make them miss.
