![Question](https://www.rx7club.com/images/icons/icon5.gif)
The car has been having idle problems right after start up, upon vacuum testing my motor I ran across these items that need attention. I appreciate very much anyones time to answer my questions, thank you
The car is a 1991 TurboII
1.) This line is leaking air at the fitting, its a hardline underneath the intake manifold, what is it?

And a close up shot

2.) Next my question is should this air pressure relief valve be routed with a hose to my intake pipe and recirculate, or should it vent to atmosphere as it is currently doing? I am not talking about my Apexi blow off valve, lol.

3.) Last one. What is this sensor with the cut wires, and what does it do?

First one is your oil injector vac line. The hose should not be hard. I would replace it with a new silicon vac hose. The hose should be attached to a four channel splitter plastic piece towards the other end of the upper intake manifold next to the firewall. Just watch out, the four channel vac connector is sometimes brittle.

arghx is right about the size. Usually those old hoses become really hard and very brittle due to heat. I would just replace them along with all other vacuum lines that you have.

ACV I believe. Well thank you have both have been very helpful. Now all I need is the identification of 3.) that cut sensor and I should be good to go until my next encounter. Learning as I go
