Motor idles fine but won't run smoothly above 2500 rpm. Reset LHM?

What is your question?

I've replaced spark plugs, coil pack, throttle body, fuel pump, MAF Sensor, Upstream O2 sensor, none of which changed the performance above 2500 rpm. also attempted to reset LHM by removing cables from battery and holding them together for 10 seconds. No change in performance above 2500 rpm. Please help!
