I have been experiencing a check engine light and poor gas mileage for the past 5 months. I have had a P0442 evap leak code but the ex passed emissions and on a scanner it shows that the evap system is ok. Every time I have reset the PCM the system monitors report inconclusive but all of them, including the evap system, give the okay after a few drive cycles. Also, my cheap scanner and my mechanic's expensive unit give erroneous values for most of the engine parameters. For example, all of the fuel trims are -100 and the oxygen sensors report 0.0 volts. He says the PCM is shot and I'm starting to believe him.
Today I pulled the PCM and open the case to find two bloated capacitors. One of my friends who is an electrical engineering here at school replaced them for me but it hasn't seemed to make any difference as of yet
I guess my next step is to replace the PCM... is it safe to buy one from Autozone or O'Reilleys? I realize I have to get it programmed by Ford after I purchase it...god knows how much we all love the stealerships
