Can anybody tell me if I am able to swap a PCM out of a 1998 ZJ 5.9 into another 1998 ZJ 5.9? I read somewhere that they are supposed to be program to each individual vehicle by VIN#. I've been having some stalling problems with one of my ZJs. I have two of them. The other one is running good still. Knock on wood, lol. I just want to make sure that this is what the problem is before I order a replacement one. Thanks.
