The thing is, with this case, that Alan had no proiblem like this before he sold you the car. Now you have had some extra electrical work done on it and nobody knows, not even you because you didn't do it, what happened at the shop or how "your guy" did everything. We all know by now that the PCMs are very tricky, sensitive creatures and if "your guy" threw some extra wires in there and now something's wrong, it looks a little obvious.....
