Annoying sound - Help Needed

[ahmedshaikhani]

Hi everyone, I'm using 4G92 Mivec Generation 2 from CJ4A chassis. I hear an annoying sound when mivec engages, the sound is like tuk tuk when mivec engages. It's not so loud also, the driver has to be very conscious in order to listen that sound. Please help me with this problem thank you.

I suppose you are running with RON95 so when Mivec engaged the tuk tuk sound is most likely the "knocking"

I am driving Mivec too but CA4A (1st Generation) on a 18 years old Satria but I am still using RON97 but now the Mivec is my weekend car so I will not feel the strain of having to pumpo RON97.

Once your tank empty try to fill up with RON97 and see the tuk tuk sound is gone.

Good luck
