Where AAC valve lies

[lenientism]

Struggling with too high RPM of the auto. The gas cable has been adjusted at its best in order not to increase the revs when being idle, RPM lowered down to level 1,100 from previously 1,300 by it.

However it's still too high so that shifting gear can't go smoothly. It shouldn't higher than 800 RPM. Having tried to find out AAC valve which probably can adjust idle to the more desired level.

Can you enlighten me please?

Here is sketch of the engine, I tried to loose tightness of gas cable (a). Actually there is a screw base adjuster (b) facing to beneath on body throttle, but difficult to adjust it. I'll try again to unplug the base and adjust the screw.

The picture doesnt show enough.


On modern cars, the throttle balde would normally be shut, or very close to it. You most certainly should NOT be having to adjust the cable to adjust idle speed.

If the idle valve is finctioning correctly, and throttle closed, then if your idle is high, you have an air leak.

Perhaps I can fault the idle valve, it might be clogged dirty, I'll try to clean it up, if not I'll put it off...
