Just bought a 76 280Z which will be my daily driver for a year or so. Not perfect, but I have the same feeling as when I bought my 87 Monte SS, really excited!
There are two main issues I am concerned about right now...
1. Car runs rich, ie blackish smoke from exhaust. It is fuel injection. I put new plugs in (NGK) and new fuel filter (purolator). Can someone lead me in the direction to fix this problem? Gas is too expensive to waste!
I was thinking along the lines of a sensor or the coil, etc..
2. Heater/ defrost doesn't work. It blows air, not hot though. Defrost selector won't work, never blows air out windsheld vents, just vents. I am thinking heater core, maybe the heat door is stuck closed, and for the defrost I don't know. It will get COLD here so it is pretty much a necessity. The two vacuum lines from the firewall by battery are broken and I can't find any open ports or diagrams. I am 99% sure these are the two vac lines from the heater/AC control. Where did these connect to?
Thanks a lot, I am looking forward to working on my Z!
I also have an 87 Monte SS that I have partially restored all by myself, which I am very proud of, so I am pretty mechanically able and willing to get dirty to fix em.
