But it is that thing you have connected between the air filter and the trotthle body.

And you have a black one original it's alu. Coloured
Oh, Yes. I the early Mercedes engines in the US didn't have a Mass Air Flow Sensor so my setup didn't require one I'm using the IAT sensor(Intake Air Temp)

If you mean the Idle speed valve. That thing kicked my ass when I got to that part but I did get it to work then I ripped it out because the method I used developed a leak.

If you look again on my pics on my build you would see where I made a hole in the intake plenum, next to where the throttle body is mounted.

I drilled the hole with the intake still installed on the car, If your intake is off it would be better to have a hole drilled and insert a piece of aluminium pipe and have it welded.

I epoxied mine and It developed a vacuum leak that drove me crazy.

The red arrow points to the pipe I installed to control the idle valve, **It must go into the plenum** AFTER the throttle plate and the other end must be connected BEFORE the throttle plate.

Hello again,

One more question about iac-valve,

From air filter i use aprox 20mm pipeline into the iac-valve, but out and into the lower part of inlet manifold, i modified the egr pipeline to a inlet for iac.
Mabye think it is to small inner diameter? it is aprox 13mm.

I also use the original egr inlet hole may i have to dril a bigger hole?

Maybe not, it might work that way. Post some pics so that I can see your exact setup.

And remember the IAC is only for controlling Idle, so I think 13mm might be fine.
I believe my IAC port was too large and that can contribute to unstable idle.

Because of too much air in bypass to meter, so theoretically 13mm might work out ok... Post PIC man.

Nice!
It depends,
you can block them or if any thing else on the engine needs a vacuum source you can use those.

One thing that I notice is the location of your IAT sensor, the further away from the throttle body it is the better it would be.

I had mine exactly where yours is but then I connected an intake duct pipe and moved it as far as possible so it can read cold intake (dense) air.

Look carefully at the duct on the video and you would see where mine is plugged in, It ran much, much better.

Sounds AWESOME!!

I can see where Yours are placed, but i`m gonna have the Stock airfilter unit on top here.
Does the iat sensor have to be placed after the airfilter?

Thanks.

Usually the IAT would be 1-2 inches after the air filter on OEM fuel injected cars.

In your case that engine wasn't ment to be EFI so you would have to adapt it accordingly

If I had your setup with the stock air filter I would first try the IAT BEFORE the filter as close to fresh air as possible and see how the engine runs.
