just remove your balance shafts all together and be happy... that way you wn't have to worry about the balance shaft belt breaking in the future inturn taking out the timing belt. If it happens you will need another new engine or at least a new head

1. visual inspection of the motor mounts. 2. ensure the spark plug wires are correctly installed. I've seen instances where reversed plug wires caused a simliar vibration.

Re: bad vibration 4G63 engine
Do you get the vibration when standing still and engine @1800-2500rpm? Or are you driving the car? If driving, what gear are you in or do you have at?

glad to hear things are back to norm Zy! I know things like that can drive you . It's amazing to me the time, effort, and costs the 4G63 engineers went in designing something that seems to cause more problems than it resolves -- but nothing of course a little reverse engineering can't solve . good job and thanks for following up on this post!
