Sounds like you need valve cover gaskets for the oil on the spark plug threads. The gasket between the plug holes and the head deteriorate.
As for the knock sensor issue, the poor acceleration is a classic symptom. When the computer detects a bad knock sensor, it retards the timing to prevent spark knock which causes uneven acceleration.
Did you actually hear spark knocking?
