I have a 1997 Mitsubishi Eclipse 2.0L Turbo (5 speed). My engine is vibrating between 1900 - 2500 RPMs. The vibrations gets worse in higher gears. When stopped, revving the engine does not vibrate the car. Other necessary info...when idle with nothing on inside the car, the engine pull approximately 15 Amps off the Alternator. When the cooling fan and ac are on the draw reaches 52 Amps. These numbers seem high to me but I could be wrong. Any ideas?

 

could be the balance shaft belt. or it could be the engine mounts.
