Do you look at the tach when this is happening? If it drops below 1000 rpm, you probably need a MAP whack, or new MAP sensor.

our engines dont like going below 1000rpm, they're too high strung to idle that low. that plus stiff motor mounts equals lots of shake. if your car is doing this alot then take nikosx's advice.

ya man...thank you!
i correct my mistake...
my engine does not always go below 1000rpm...
when it drop below 1000rpm the shake start....
and my rpm is sometimes a little bit fluctuate
ya...and when engine start up cause some shaking too...
it maybe the engine mounts and the map senser!

anyway thanks alot man!

any other advice?

i doubt that it have something to do with the rpm....according to some member..he said the rpm wont go below 1000rpm..and the annoying vibration happened when the rpm hit below 1000rpm...(rev and drop)
