Noticed that the steering feels boosted when the engine is just idling. So I took a closer look and saw that isn’t vacuum hose. Got some vacuum hose and also bought a cheap ass check valve since it seems to me there should be one between the manifold and booster so the engine doesn’t pull air from the booster. Only drove it a few blocks but the initial pedal feel is noticeably different, now it actually feels like there is a booster. Steering still feels heavier while driving vs creeping. Not sure what’s up with that, maybe the booster is too small? Not sure need to learn more.

Also discovered the trunk leaks, quite a lot. Going to replace the gasket and check alignment. Also make sure the c pillar vents are properly sealed. Hopefully it’s an easy fix.
