Re: 2000 windstar 3.8 engine out of balance

Although rare the Harmonic balance pulley maybe bad.. So when in park and you rev the engine a bit does the shaking or vibration stop.??? Is the coil pack good or ever been replaced.? Sometimes you wont get a code until the coil pack goes out. Usually a flashing CEL light when this happens.. If you cant find anything else wrong you may won't to have the harmonic Balance pulley checked out.. The only ones I have seen go bad like that have been in an auto accident and the damaged body was repaired but they had a vibration do to damaged balance pulley.. But for the most part what keeps a motor from shaking it self apart is the harmonic balance pulley hub..
