Default Disconnected vacumn hose???

My ZR1 is running like crap, missing at idle, missing running through the gears, and stops running at stop lights. I started looking in the engine compartment to see what I could find and I found this hose connected to a smaller hose on top of the power steering pump that was disconnected at the bottom. I could not find a connection for it anywhere. Anybody know where this hose is supposed to go? Pictures are on this post (I hope)! Thanks!





the hose on the left





the hose with the golf tee

it t'ees in right where that other hose is connected. That second hose shouldn't be there. The right angle T that is capped off is supposed to have a short hose going to the air injection diverter valve. Perhaps they ran a replacement hose due to some leak in the hard line or ??

Check the MAP sensor hose at the rear of the plenum.
