labrat Posted September 10, 2001 Share Posted September 10, 2001 I have a problem that someone here might be able to help me out with. I have a stock 1980 280zx GL with the automatic climate control system (vacuum controlled vents...). Anyhoo, I'm checking under the hood for vacuum leaks to fix the popping out the intake while it's cold, and i hear vacuum sucking through a little device on the manifold right behind the throttle body. Does anyone know what this is? i covered it with my finger and the idle dropped about 300 rpm. Is this a "leak" or is it supposed to vent vacuum? thnks for all the help in the past...
