A week ago it started acting up, cutting out when I stood on the gas. Friday it flashed the check engine light eratically all the way to work. After that, it has started idling fast, and shortly after cranking it will jump to around 1500-2000 RPM and idle that fast until you put it in gear to pull it down. It has also idled up and jumped out into traffic a couple times. The check engine light blinks 3 times right after startup, but I couldn't find out what that meant. Anybody know what it could be?
 






I would determine the origin of the CEL illuminating.
 






Run the EEC-IV self-tests. I recently found an easy to read description of the KOEO test at www.fordfuelinjection.com only takes a paper clip or equivalent.
