The harmonic balancer was found to be torn. Van had around 120K miles at the time....merry Christmas guys

It has a terrible vibration too, for about 15 seconds from a cold start, throwing a code that says misfire in the #1 cylinder. So trying the hit or miss tactic, I replaced the spark plugs, which I hope to never have to do again on a Trans Sport. This pulley fell off as soon as I started the engine back up after the spark plug job.
