When taking off from a complete stop i can press the gas pedal to the floor and the acceleration is like and old dog running up a hill. It will get up to 60 miles and hour but it take a while. While the vehicle is Idle the engine sound go and gas pedal response is good and this is when the vehicle is in park and i am reeving the engine up. I have change the Vapor canister sensor , Idle control sensor,air filter, cleaned the mass air flow sensor and clean the throttle body. Maybe its the cat? but which one would it be.

Will it rev up if you manually put it in low gear instead of going through the gear range automatically?
It is possible that you have excessive exhaust back pressure. Not quite sure how you'd test it though... You can disconnect, exhaust at different parts and see if (ignoring the noise) it accelerates better.

Have you looked into replacing the ignition coils? Your symptoms sound just like mine when I first got it, my dad swore up and down that it couldn't be the coils because they weren't throwing codes. Three junk yard units later and I was able to spin my tires, huge difference.
