20V engine idle speed

Hi feipepe.

Here is the picture where I installed the air regulator. I think it cannot implement on AFM system coz AFM is sensitive to vacuum leak. It measure how much air entering the combustion chamber while map sensor measure pressure inside the manifold.

Slightly vacuum leak at AFM system also can make rough idle.

Alex, you just need to put back your original trumpet, and tighten up both end of your ram piping.
Please buy a new tightening clips. Your existing clips already worn out. When tightening, make sure both joining part is align.

Thicker oil like 20W-50 will actually increase engine resistance and temperature. I recommend to stick to 5W-40.

When come to isc/iscv and air bypass screw. Don simply adjust. Idle will go crazy and u are cathing own tail.
I have bad experience. lol....
