Recently, I discover that my engine will tremble and Vibrate before
I shut off. Problem is, this issue doesnt occurs everytime. More likely
to happen when I turn-Off the Aircon and engine still running. Gear in 'P' and it will
trembles and Vibrates, RPM drops for that few seconds before it
suddenly rev up again to prevent engine stalling.

What could be the problem?
I have my Plugs changed, Engine Oil renewed and Filiter change
as well. Problem still persist. Could it be the sensors issue or
Idling problems? Nothing of this sort happens when Gear is in 'D'

Ya, engine mounting might be due for replacement. If you have experience mechanic, he'll use his hydraulic jack & jack up your whole engine to determine which mounting spoil.
Engine mounting replacement costs around S$ 120 to S$ 500 or more depends on how problematic for the replacement & usually each engine having 3 mountings.

Alot of advice to clean the TB and Idling Controller.
My Mileage is high @ 260K and its a 7years old Stream running on D17A
engine. Just recently that I had this problem. Not everytime before
I shut down it will vibrate. High possibility when my Gear Position in 'P'
and A/C just turned off. The engine will trembles like its going to stall
and moments later, the Rev will build up and save the stalling engine.

Did you try switching on the head light, put them to high beam and turn them off to see if the same symptom appear?

The idea is to load your engine with the alternator and remove the load suddenly to see if the ICV will adjust the engine speed smoothly.

Have you changed engine mountings before? Maybe it's time.

Engine Mounting Changed @ 160K. These Mountings are still fine. Except that the Engine Trembles and Vibrates
before shuting down. That's the problem which I am facing now.
I will try to load the Alternator and see if it loads the ICV.
Talking about Loading, think should be the relating root cause as when
I off the A/C with the Gear in 'P', possibility of the vibrating is there.
What I felt is the RPM doesnt compensate the easing of load at that moment
thus creating the problem. It will rev up seconds later.

Hi, Bro Godfinger,
Sounds to me the air-con compressor relay might causes these problem ? Please let the air-con mechanic to look into it before replacing any parts that may be wasteful.

Worrying is like a rocking chair,  keeps moving you forward and backward forever wasting your time and gets you to nowhere.

Mounting checked and is still
Useable. Only suspect now could
Be the ICA or TB. Shall rule out
TB since idling when waiting at
The lights or more specific, when
Gear is in 'D' is perfectly normal.
Could b relating problems with
Loading since problem only happens
When A/C is shut off.

Dirty fuel filter or choked injectors?

My engine is able to rev willing.
