car vibrating when idle

[drill]

hi all,

i hv a kancil with ejde auto engine (similar engine to kelisa)...

the problem is, when i put into D or R and puts on the brake, it will shake the whole car.

i've noticed that this occur when the rpm is less then 1800, this problem will occur.

all engine mounting has been changed and firing on each plugs are ok.

Any suggestion what else to check?

tried to increse the idle timing to 2k rpm, then its ok. but i think its not normal to idle at 2k.

also i've noticed that if let say on a Neutral gear position, if the idle has been set to 2k rpm, once i

put into D or R, the timing will drop to around 1.3K. Please help.
