running rough

[dewdew]

i was just driving my car, not even being hard on it, and all of a sudden it started running really rough. like everything in my car vibrates. The engine still seems to run fine and it seems to have its power ( didn't really get on it when this started), and all vitals seem good. have oil and oil pressure. no knock. good timing. what could this be. kinda sounds like exhaust came off slightly making it louder and feel more vibration but that is not the case. just had the motor fully rebuilt.

 

[uh-oh]

sounds like a broken balance shaft belt to me

i have a b-shaft eliminator

 

[uh-oh]

and no bad mounts???...i really wouldnt know unless i heard it

its vibration all the time, even parked just reving, coasting, driving, and the exhaust has a deeper tone to it

I just found my vibration problem, was the same thing. always vibrates at any rpm, clutch in or out, whenever. I found a damn bolt wedged between the tranny and crossmember causing all of my vibration!
I was pissed and excited all at the same time.
