ok, got a new car and its LOUD. basically, when idling you cant hear anything, but whenever the engine is putting load into the wheels there is a loud noise - sounds like it could be the exhaust blowing but it isnt, because you can feel the vibration of the noise thru the acc pedal. let off the gass and it dissapears - i can find the point where it 'starts', and if i hold just below that the noise comes on whenever the car goes over a minor bump in the road - similar to when osmething was hanigng off the bottom of a different car, but theres nothing hanging off. ANY ideas? i'm guessing some bearing or other.. or maybe an engine mount? its a volvo 340, which is a rwd car with the clutch at the front.
