Have to push the rpms way to drive

I have a 2000 Mitsubishi eclipse. As of about a month ago it started driving kinda odd. It started having slow acceleration issues. I usually stay around mid to low rpms and have lots of power now even in reverse I have little power and have to rev the rpms almost up to red line to get it to go. It is a five speed and it takes a while to get up to speed but once there I can maintain it just hard to go any faster. The check engine said the map sensor was an error code so I replaced it. I replaced all plugs and wires, mass air flow and filter and one of the O2 sensors still no power. 

            Please Help

Did you check the fuel pressure?

A clogged fuel filter can cause a no power problem.

Check the fuel pressure, low fuel pressure or fuel volume can also contribute to the problem.

It is rare but a bad knock sensor will retard the ignition timing. Rescanning the computer and look at the knock sensor and timing parameters will help find the problem.
