Hey guys when im driving and stop at a light i hear and feel loud vibrations from the motor or tranny i cant tell nor can i honestly enplane it. When i put it in Neutral or park te vibrations stop but i can still hear something knocking. When im moving i dont notice anything wrong.
and i also changed the SC coupler bc it was bad causing more noise

my dad says it sounds like a misfire but no check engine light comes on and it performs the same. i ordered new plug wires though
 


Next time you're outside, pop the hood and start the car. Look at your harmonic balancer (crank pulley) does it look to be spinning off center? If so, the pulley is bad and causing your vibration
 
there is a pully that shakes but i swapped it and iit was still moving it was a idlerpulley but i will look if its moving
 
I'm talking about your harmonic balancer. The crank pulley at the bottom of the engine. If that's shaking, then the rubber has deteriorated

I have the same issue and i noticed that you can just buy the rubber seal. Im looking for a write up on how to change the seal but couldnt find one. Any insight?
