First time z owner. So i just bought a 1990 z non turbo, it has 118k with all new tune up and clutch, a/c blows but is not hot nor cold. Runs absolutely fantastic except one problem. Whenever i drop it into neutral the idle will fluctuate from 100rpms to 800rpms and sometimes even shut off. Now when i have the defrost on, it will idle at a constant 1000rpm.. Weird problem, so i went underneath the car and i see on the right hand side there is a tube completely disconnected and the part it connects to is completely missing. It is right next to the wheel base on both sides you can see I have included pictures for you guys to see the left side is connect but the right isn't. Also i have exhaust gaskets i need to put on do you guys know how hard it will be??? I have pictures below.
