Oh no!
My Forte is now plagued by the 'Helicopter' sound syndrome.
Situation where the helicopter sound occurs:
1) During acceleration of the vehicle (at low RPM range: between 1K to 2.5K RPM mark)
2) Accelarating/Revving the engine whilst stationary (gear shift in Neutral mode) at the same RPM range.
NOTE - I've tried revving/accelerating with both the Air-Cond turned on & off. As such, I'm not entirely convinced that this is an Air-Cond Compressor issue

My conclusion:
It shouldn't be the stabilizer link as te helicopter sound can be heard even during stationary throttle revs.
However, I've yet to be able to pinpoint the exact cause of the sound/noise.
Anybody has any other opinions?

mine tested stationary/handbrake/p, press press pedal oso no sound come out, tested with ac on/off.
only got sound when moving with ac on, for maybe too soft until i cannot hear when ac off.
read from forte forum, there is some heat shield or something near exhaust is loose, oversea got memo for that
