Y'know David, it's not often that I get to correct you, so if I get the
opportunity, I'm gonna damn well jump on it.
The "auxiliary air regulator" does indeed sit on top of the 1.9 and just
below and to the left of the AFM. It's kind of an anvil shaped doohickey
that allows extra air into the engine on cold starts (the logic of which
escapes me as I thought you would want a richer mixture for a cold start).
It has an electrical contact on one end (connected to a heating element so
it won't stay on too long) and an air hose coming out each end, one of which
goes to the rubber intake boot.
This part is NOT this gentleman's problem, but it DOES exist.
The hunting is probably from a too lean mixture at idle, but you know that.
Most likely bypassing the idle stabilizer won't do much for him.
