A question about auto electrics

I have a 2005 dodge truck with a 4.7 that has started running very rich to the point of choking out and it has a random cylinder misfire. The cruse was working intermittently and the dash lights would randomly go on and off. The mechanic changed a coil and cam sensor that did nothing but clean up a couple codes and suggested I change the ECM.

My question is: can I use a junkyard unit that I can change myself or does the new computer need to be reprogrammed for my vehicle by the dealer (I have heard both)

no forearms clause for in-store.

Don't that make it hard to get parts off the shelf? ;)

He should have waited till the perp exited the Store.
