Yep.  
Car had a CEL for a bad 02 and knock sensor.  
A retarded monkey with a wrench could fix those. I doubt anything went wrong even if that knock sensor is a complete bastard to get to.  
The car was running worse prior to changing those parts.  
But this pulsing issue has been ever present.  
Also wires and dizzy were the original so it was under the maintenance list of items.

Timing has not been set and should be.  
Better yet, What should it be set to?
