Thread: Very noticeable vibrations when not moving in drive

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

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 looked and it is moving looks like ill change it thanks man

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?
