2002 Saturn L100 dying after 4000rpms

I have replaced the coil module, ignition module, boots and plugs. It was sucking oil from the vent tube through the throttle body causing fouling plugs. I blocked that off to see if the condition would change. It continued to die off after 4000rpms but now it makes a click (like a solenoid) then acts as if it is sucking wind and the tranny won't change out. Now if you reduce the rpms it will start to run like normal, but with a minimal loss of power.
