I just bought a 98 Deville with the 4.6 Northstar and there is a fluttering sound (from the exhaust I think) during acceleration, and goes away when coasting. Any one have some ideas about what I should be looking at?

Is it coming from the exhaust tips (misfire) or upline somewhere (exhaust leak)?
