What is this thing??

Post by jagni401 »

This is off a 2L hilux, and I have no idea what it is. Is it some form of choke?

When it's cold, the engine tries to idle around 500rmp which is pretty low, and it struggles until it is warm. When its warm its sweet as, and sits around 700rpm.

Image

When I change my vacuum hoses, the small rod moves forward, and the idle speed increases, and t runs better. However when its warm, the idle speed goes from 700rpm to 900 rpm (ish) Is this too much??

Image

Currently the vacuum hose to the idle thing has no vacuum through it, so I suppose the small box with the vacuum hoses going into it need to be rearranged??

Image

Can i move the screw to adjust the idle speed manually?

Any ideas??

Cheers

I think its for idle up when accessories are on like Air Cond...??
The thing below it with the two water hose controls pump timing so its not so lumpy when cold..(retards it a tad)

Anyone else care to comment...
