Recently our Eclipse with 3.0 v6 starting cutting out when excellerated. It will idle all day, and when you get it up to speed it will run 80 all day, but excellerate fast it falls on its face and will not pick up until you let off, when going down the road I can downshift at get speed back up.

Runs great cold.
We have had it to repair shop and Auto Zone. They have replaced fuel pump, two of the oxygen sensors, mass air sensor, plugs, wires, distributor and rotor.
They now say the pcm needs flashed?
Codes still say oxygen senor and missfire.

We are out of money or I would just take it to a real shop and say fix it.

Try reflashing the computer. If the same codes still come up, that is where the problem is coming from.
