Fires up ok when cold, sounds like it skips at idle, but when you rev it it hits on all faces, or sounds like it. Steady throttle it has a bit of a skip, like it's running too rich or lean, TPS needs readjusting too though. When it warms up, then it sounds like it loses a rotor and won't idle, has no power. When cold, it has plenty of power.

Sound like an EGR problem? or something else? If you try to restart it when hot, it just floods itself out.
