I have a 2005 Ford Five Hundred. My engine light was on and the car started misfiring. Went to AutoZone and they code checked it with their machine and it said that the third coil pack was bad. Change that and the spark plugs. It still jerks and now when I accelerate the engine light blinks. Anyone know what it could be? Thanks in advance.
