We need to run the codes to see if any are stored, it sounds like the car is in limp mode, and this will help us see which system is having a problem. Please go over these guides to help us see how to fix the problem:
Here is the location of the MAP sensor so you can swap it out. Also is the engine misfiring when accelerating? Please check the air filter as well. Check out the images (below). Please let us know what happens.

Replaced all they above MAF, MAP, and new cat converter and exhaust system. Also, I have tried it completely unhooked and still the same.

Can you upload a video of the engine running so I can hear it? Also, can you double check the fuel pressure? here are two guides to help, you can rent a fuel pressure gauge from the auto parts store for cheap or free.
Fuel Pressure .................... 48-54 psi
KOEO Key On Engine Off
Please let us know what happens.

Did you check the air filter? Also, when the engine is idling do you hear a rattling sound from the front of the engine? Can you upload a video of the engine idling and then rev it once so I can see, I think you may have a timing chain that has jumped. Check out the images (below). Please let us know what happens.

The problem was a broke coil! It shut down 3 cylinders, but the vehicle never missed a lick just would not rev up (accelerate). Thank you very much for your help.
