Do you have any way to put the car on a dyno? Without seeing a graph it will be hard to tell what the problem is, especially since it seems valvetrain related to me.

today i started to change out the plugs to new ngk tr6,and at the same time,do a compression test.
all cylinders on the driver side was ~190psi.
I will do the rest tomorrow.

dyno is expensive here,a full dyno tune costs 1200

Yes that is where you would want the test to be at. Is the car throwing any codes or making any funny noises? Is the valvetrain really loud?
