There used to be remans available -- don't know if that's still true. Might try a little web searching.

I did buy a junkyard PCM once (mopar). This was a pretty big place and they had them in inventory. Asked how they knew if they were good -- said "we take them out of cars that still run. "

I have heard of Ford PCMs and bad electrolytic caps before. Some guys have fixed them by replacing the electrolytics.

But, do yourself a favor and check the EECIV relay and other power wiring too. If you have crappy power the PCM will act up.

Just my .02 -- good luck,
