You could use a 12vdc solenoid to open a vac. line. Grainger has them for 25 bucks. would be open or closed though, nothing in between.


Yeah, I was noodling through that idea myself...could you put a potentiometer in the circuit and control travel of the valve piston on a solenoid air valve? Control the POT from inside the car...no cables needed?

Just getting a AAR for a 924 is probably the easiest, but not as much fun.

I live in the Northeast.
It was in the 30's this morning.
I have NO AAR and NO cold start injection.

Car starts fine.
Idle the car for less than a minute...enough time to close the barn door.
Drove to work...no stutter, no stumble.

When it gets down to less than 20 degrees, I need to warm it up for a minute, maybe a bit more.

I drive to the end of the road in third gear, about a mile.
Heat is nice and hot, car runs great.

I also tune my car up frequently and mess with the points and timing frequently...and adjust my valves frequently.

Rich, thanks...its maybe 44 here in Northern California, but you know our reputation for being squishy. I have upped the RPMs via the idle screw when the car was warm, and we'll see what effect that has when cold. That may take care of it.

Take a look at Brad Anders' site. It will really help with understanding how this system works and what components can be interchanged. You can't just get any old AAR.

No, in a nutshell. A solenoid by nature is open or closed. Variable voltage would only make it start to get hot, then as the voltage increased to the minimal coil voltage, it would just trigger. You can get a servo valve, but it would cost way to much. You possibly could hook up a small RC servo as a variable idle stop, using a pot or even a small servo driver board. Or use one to open a ball valve, as long as it wasn't a stiff one. Lots of ideas, not a lot of time.

You are talking to a bunch of guys that cant even decide what weekend to get together some days...and then many flake out.

Hearding pigs or cats may be easier than getting a collective decision from this group.

Its amazing how much energy is spent on a part that is still available...no need to reinvent anything.

Here is one source... (IMG:style_emoticons/default/biggrin.gif)

Just get the right part and do it right...
