Underdrive Pulley Wobbling
Any ideas???
If you want to check the crank, remove the pulley, get a dial indicator, un-plug the coils and have someone turn the motor over. If the dial fluctuates then the crank is bad. That would be doubtful though.
Most likely the pulley wasn't seated all the way. Unless you torque that thing down to 200+ ft lbs it's not tight enough.
