Tonight i was out for a cruise, when i came to a red light and started to slow down i thought i heard something like a bolt fall off my car and hit the ground but i'm not sure that's what it is, it could have been a rock in the wheel well, anyways after that the car started to shake really bad even at idle it shakes bad i do have a huge cam in the car but it shakes way worse than it ever has and as i left the light it shook worse until i get into higher rpms then it levels out a bit but i can still feel it pretty bad. any ideas? thanks guys.

 

Before I do anything I would check for pending codes. Could be something simple like maf, wires or plugs. I doubt it is anything serious.... Any unusual noises from the car?

 

I think it might be my clutch/ flywheel a weight fell off I think and it threw it out of balance.
