In my 98' SE 2.5L MTX I have noticed that around 2500RPM or so, I have a relatively bad motor vibration... as if the motor was VERY poorly balanced from the factory. I have been seeing this dual damper deal lately that supposidly eliminates excess vibration and am wondering if it will help down low or if it only helps up top which it is advertising. Is this a common issue with the 2.5L? Will the dual damper or anything else out there help this outside of getting the rotating assembly balanced?
