the engine is vibrating & shaking badly at idle. idling 900rpm steady. above idling no vibrate.

as i know , throttle body dirty might cause rpm to dance up and down
but my rpm is steady, just the whole engine vibrating badly
on the road, the power is normal for a stock gsr

tune your ignition timing and check your cam's timing with your crank shaft. your cam overlaps timing might be off-ed
