[Rod80SC]

This all started back in december and I have been stumbling and bumbling and dumping money into her since then.
First symptoms were jerking, coughing, fluctuating tach and stalling after warm-up. I could nurse it home if I just idled. Any attempt to accelerate would kill it. Other times it wouldnt restart at all until it sat for 5-10 minutes. Then start fine but unable to accelerate.
Heres the wierd part....when the tach starts to fluctuate the brake and oil light also flash.
First thought was coil so instead of replacing with stock I did the winter MSD conversion along with plugs, wires, cap and rotor. Following first test drive exact same results. Started great ran fine until warmed up. Pouring over the archives here I found the culprit may be the green wire. Repalced that and still have the same results.
Thoughts.....how does the brake and oil light tie in with all this (obviously a ground somewhere).
14 pin connector ?

Any help or advice is greatly appreciated.
