Idle Stabilizer Valve

["John \"Magnus\" Altinger" <altinger@max-net.com>]

Does anyone know exactly where this Idle Stabilizer Valve is on the 
motor? I see where it plugs in, but is the plug in, the actual valve?
My '84 5000S idles fine after its warmed up for 2 or 3 minutes of 
driving, but idles crappy when cold. I assume a new valve would fix this 
problem.
 
I'm just wondering if its a quick fix, or I have to gut the engine to get 
at the sucker. 
 
I have the Haynes manual, but it really does'nt mention the valve much.
