is it possible ignore those OEM IAC and achieve stable idling engine speed?
i've dig out the original Auxilary Air Regulator of my 3TC and i have MS II on Ver3 board.
how can i achieve my goal?

I went a few months in winter without idle valve.
You will just have to hold the throtle open manially untill the engine warms up... or set the idle very high so it keeps running when cold.

I finally hooked my fidle valve up and it is much nicer to start now.
The simple on/off type idle valve is quite trivial to hook up compared to the rest of an MS instal. I encourage you to do it now... because you will eventualy

Hi all:

You can also fit an old style choke/starter that opens the trotle manually, and a light to where the IAC must be, and pull the choke while the light is on, and push it when the light turns off.

Juan,

I had that idea too, then I realised how much easyer it would be to install the fidle valve instead of running a push cable, levers and lights
And probably cost less in parts.

Hi:

The thing is that my cars at the operating room are so old that already have this installed

Try with a simple canister valve (a very soft and cheap installation as Jedrik states) and if is not sufficient air volume, open a litle the throtle with the idle screw.

if i would using my OEM auxiliary air regulator, how should i wire it up on the V3 main board? it just only have 2 pins..is auxiliary air regulator same as the Fast Idle Valve?
