Hello 2 those who can help me out with my Kancil turbo problem.

I'm using a standard Mira turbo EFI engine on my Kancil. My idling rpm is unstable and giving a sound like a naval attack boat. It's so irritating to my ears. Some guys said that its due 2 the throttle body. They might be correct.
I tried 2 clean the system by removing the turbo intercooler and spraying the crc carburettor cleaner direct 2 the throttle body, but there was no effect. Next step I want 2 do is cleaning the MAF...
