My truck usually of a recent experiences low power when accelerated.
My 3rz engine works perfectly on idle.
When accelerated, the engine revs good and fires well but the truck drags.
It looses power to respond to move.
And when on load, is worst. It drags even though one can hear the engine raising normally.
I do not understand this.
What can I do?

It sounds like a classic plugged catalytic converter which causes low power much like what you have described.

Here are a few guides to confirm the problem and get it fixed:
