Sounds to me that your shop is a "parts replacer" and isn't following diagnostic routines to isolate and fix what's really broken. Some shops simply don't have the equipment necessary to find problems and use hope as the technique ... hope that if they replace enough parts they'll actually replace the one that is causing the problem!
So far he has put in 12+ hours trying to chase down this electronic gremlin, replacing several blown fuses after the MPM replacement, but to no avail. I finally got a code to stick tonight, but it makes no sense (bank 3 O2 sensor short circuit). The Electronic malfunction flashes, along with several warning lights, but does not throw a code.
