think this is a purge control valve, it's off of a 1996 Monte Carlo SE 3.1engine. Does anyone know if there's a vacuum line supposed to be connected to where the arrow is pointing? I was changing spark plugs and noticed that nothing was connected there and I can't find a loose hose anywhere. Please help.
Thanks, Dennis
