VIBRATE ON IDLE !!!

1992 Suzuki Swift • 150,000 miles

Swift 1.0 cc 3 cylinders
the problem is the vibrating on idle
i've changed the motor mounts and the transmission mount and still have the problem
some says that the 3 cyl engines vibrates more than th 4cyl engine
and its normal to feel this vibration on idle with the 3 cyl engine
is that true !
do I realy have to feel this vibration on idle because of the 3 cyl engine nature !

I think they do idle less smooth but have you taken compression test to verify = cylinder pressure?

No I didnt yet, do you think it might be a cylinder pressure problem !
Cause some website sayes on the suzuki alto 2009 car review
that Inherent in three-cylinder engines are noticeable vibrations at idle - you soon become accustomed.
The point is I feel exactly like if I drive a four cyl car with
a damaged motor mount. Is that what they mean a bout (noticeable vibrations)
p.S i've just bought this car 1 month ago and I never try to drive the 3 cyl cars before thats why I am asking !

You only need a minor tune problem for these little engines to cause a problem, so do the comp test and general tune, vacuum leaks as well can be an issue.

Yes I would add because of the 3 cylinders ANY little thing out of harmony can exaggerate an already present vibration.
