How many no braking decelerations do you need for a misfire?
The PCM needs to see at least three 60- to 40-mph no-braking decelerations for Profile Correction Relearn, which means a standard road test around the block will not get this done. •Many techs have wondered why on some Fords the Check Engine light does not come on right away when a misfire is present.
