d16z6 motor, dx auto transmission; basic I/H/E,
When the motor is cold; it has all of the power that it should.
The car maintains this power until the needle on the temp gauge is 1/4 of the way up. Then it bogs on take off, and has load issues. no matter what; the car drives as if i was barely accelerating; but when i get up to speed it takes barely any pedal travel to stay at that speed.

Any ideas? Thanks in advance.
