after 12B37 - bad hesitation, slow to accelerate
anyone else experience a severe hesitation and loss of power when accelerating from a standstill since having 12B37 done? sounds like Im having the opposite effect of others. I test drove a new 2012 focus that had intent of 12B37 done during manufacture and it ran great like mine used to. This has been going on since 6/12. cant seem to get my dealer interested in giving me any real help. I own two other 2012 focus's that havent had 12B37 done yet and they're running fine.
