83 NA doesn't want to run
Ok, here's the skinny.
Recently my Z has been bogging down during hard runs, and I had to hold the throttle open to keep it from stalling, will only keep running over 2500 rpms. Take your foot off the gas, it's like hitting a brick wall. Pulled the plugs, caked with soot. OK. It's losing bout 1/2 a quart between oil changes, so I waited too long to change em.
Autozone rotor button heated and slipped timing, due to crappy buttons with no set screw. Replaced rotor and cap.
Thought maybe not enough spark, put a blaster 2 coil in, ran crappier.
Running retardedly rich, so O2 sensor was next.
Now, car won't run at all.
Grrrr....
Any Ideas?

Welcome to ZDriver!
The main things to cause overly rich conditions are the AFM (air flow meter) and CHTS (cylinder head temp sensor). Check the connections and overall condition of those sensors. The AFM can also be adjusted.
