2000 focus was running perfect. Pulled up on Friday night and parked it. Next morning hand slipped off key after about half a second, never thought anything of it, went to start the car again and it just turns over. Solus shows error codes P1664 (Injection control module malfunction) and P1564...
Just come across this from my friendly Ford Dealer, here in Eindhoven, Netherlands.
Its a aftermarket USB add on for some models of Ford's (Mondeo, Focus and the like)
check it out, hope it helps.
