My girlfiriend has a '97 Grand w/ a 5.2 w/ only 48K miles. Sometimes under acceleration from dead stop or accelerating at highway speeds there's a drivetrain vibration. It's very intermittent but obvious when it's there. I'm thinking maybe a bad engine or trans mount. Anyone experienced this with theirs? Thanks![addsig]

Could be something as simple as a wheel out of balance. Start with the simplest posible answer and work your way up to the hardest and more expensive. Tug[addsig]

if she likes to stomp it off the line, then it could be a motor mount. could just be an idle, where do you live? in iowa its cold enough that even when my engine is warmed up occasionally it'll rumble a little and the RPM's will dip or something.[addsig]
