Has anyone ever had to do this? Why do they not sell the "prom" with
a refurbished computer at an auto parts store? What if the "prom" is
what is wrong with it? How can you tell? Can they be tested? If so,
how? Can they be seriously damaged if I were to replace one in a
vehicle that had opens or shorts in any under the hood wiring?? I
know this is a lot of questions.
