I have this problem with my '88 spider.
I have to hold the accellerator down slightly when I start it to get it to run.
Before it would start fine, but was idling too high - I assume the AuxAirValve is shot becase it's always open. So I put an "oriface plate" in. A 4-hole shirt button in the bypass air hose, at the plenum.
How do you test Aux Air Valves?
Does anyone know where I can get one of these inexpensively? I think IAP wants over $200 for one.

Hey Jeff:

Post a picture of it. I may have one from an 84 that I can give you.

Best Regards,

Aux Air Valve

I think there's a few Aux Air Valves up for bid on Ebay right now. They are very expensive new, for such a simple device. Anyway you can test it: When the engine is cold, start it up and pinch the outlet hose from the valve. The engine rpm should drop slightly. This tells you the valve is open. As the engine warms up, pinch the hose again and there should be no change in rpm. The valve should now be closed. I believe there's a bi-metalic strip inside that opens and closes the orifice in relation to heat.

Hope this helps,
