Loss of power

I replaced, plugs, plug wires, Distributor Cap and rotor. that made a remarkable difference but there's still a small flat spot at high RPMs. I have an o2 sensor ordered for pick up today. I'll install that and then clean the Throttle Body weather it need it or not and post my results. ( No CEL CODES) mine is a Manual Transmission
 
No Joy. I still had a flat spot. And when I wiggled the CPS plug I caused a major miss at Idle. I removed the CPS plugs nut and keeper from the fuel rail and moved the Wire loom to experience a total power loss to the spark plugs. looks like a replacement female CPS connector is the next step. I feel like I'm close. I'm gonna turn this thread back over to the OP and start my own Thread. I didn't think this would get to be so involved. Sorry for any Inconvenience .
