Well the dealer was unable to reprogram my used, like new looking PCM, with identical numbers as my original except for the last two digits of the serial number. They offered to sell me a new one for $1,230. So i paid the $152 for their failed attempt and drove home with my old PCM. The car still runs great, has no diagnostic codes but get 20% less fuel economy due to the intake manifold runner flaps being open all the time.
So I found a 36,000 mile 2015 Focus SE on Copart for $5153 and bought it. Will try to drive it back to Kenosha, Wisconsin from Detroit, Michigan on Monday. The plan is to sell my 2010 Focus SEL for $1,000 after we see if the Copart one is at all reliable.
Thanks for all who helped work through my IMRC issues especially Marde and Paul.
