Thank You NewZed, and JHM, most of my issues have been resolved after going through most of the circuitry of my car.
*Headlights were fixed via replacing shattered Glass Fuse
*Voltage Guage was also fixed via replacing blown Glass Fuse
*Alternator Charge issue was fixed after fixing the Volt Guage and noticing no charge light was turning on when starting the car, change the bulb in the volt gauge and the light came on but the alternator was still not charging. The issue was resolved after changing the Fusible Links alternator worked like a charm.
*Rough Idle was fixed via going through the vacuum hoses and noticed one to be broken, after reconnecting the hose car Idle was better.
Now I am trying to focus on the Brakes:
Thinking of doing the Toyota PU Calipers and 1980 280ZX Master Cylinder, and upgrading the brake lines if needed, also brake hoses as well.
Next is Ignition:
I want to know if the Stock Distributor is good or should I upgrade it?
Also, the Ignition Coil is still stock, and feel like I should Upgrade that as well to something a bit more powerful and free flowing.
After that I want to focus on the Exhaust:
I have a terrible hole or leak in my exhaust and all the fumes are coming to the cabin somehow.
Also, are there any Known Exhaust Systems available for the 280z 2+2? or would it be cheaper to go to a reputable Exhaust Shop and have them make one for the Car?
For some reason when I start the car after an extended time, I can smell a lot of unburnt gas it gets better after time but initially, it seems that car is running Rich as Hell
