vibration through Rpm 02 galant 2.4L

[Wtfman]

Hello all,

I had some good opinons upon asking questions about my 00 silverado 2500, so i got a few for an 02 galant with 92k

Upon acceleration the car will have a helacious vibration, that gets a higher frequency with rpm increase? i dont know much about these cars so i dont know what it could be. It sounds like the motor is imbalanced or something??? Harmonic balancer??? Other than that the car runs great...
THANKS

If you are mechanically inclined, you should check the timing belt out and make sure both belts are lined up properly. The balance shaft is very easy to misalign on those engines. There are multiple threads on the same thing.
