In my quest to find my Z's slight idle/hesitation problems (see my other post farther down), i began looking around my engine pay. I noticed on the passenger side, next to the engine block, is a gold metal pipe with three fitting that have thin rubber hose going to it, one from the air intake pipes going into the plenum. What is this? It was off its mount on the engine, and the rear most hose rubbed against another and was split. I pushed it on the fitting further and put some electrical tape around it as a temporary fix to see if anything gets better. Sorry, I don't have pics right now, but I can get them later. Thanks for your help!
