so , what is this caused by?... loose vacuum lines wont do this, nor slight leaks in the intake gaskets. this is a air turbulence howl that almost seems like its air vibrating the maf sensor or something.

BTW an update:
We started the car(Cold start)- The engine shakes & strong fuel smell from the exhaust. I stopped the engine & keep it parked first. I will towed it to the shop once the parts arrive. My friend will order those parts.
My friend who owns the shop will order the staffs from the internet & will look into the possible problem of my car.
I've print Dr bob's suggestion & most of the conversation here.

An update for my car.
Foul plugs seems to be the culprit. 3 of the NGK plugs head is broken when they took it off & the others have really black tips. Now the car idles OK but when sometimes randomly at traffic lights. I do feel shaking & misfire .I just rev the car- the car will be stable again.
What we did so far-
1)Change one side coils & rotors. The other side. Just clean it.
2) All new spark plugs.
I wonder if fuel filter got anything to do with this? or plugs wires.
Advice
With regards to the whistle sound- I don't hear it or maybe the loud cooling fans overcome that sound

I hope spark plug ceramic debris didn't fall in. Or if someone attempted to blow it out, the intake valve for that cylinder was closed. I was once victim to that sequence of events, courtesy of a Mazda dealer.
