I am at my wits end!! This car idles rough and has no power / stalls when placed under a load. I have replaced the following:

1. Cam Position Sensor
2. Upstream O2 sensor
3. Spark Plugs and Wires
4. Coil Packs
5. Engine wiring harness (on the top of the motor)
6. Fuel pump
7. Misfire sensor
8. Injectors

I have also cleaned the throttle body and the Idle Air Control

I have a code reader that gives codes and colored lights. No codes are flagging, but the lights for CAT, EVA and EGR are blinking red.

Is there anything else I can do besides roll it off a cliff?

Unscrew Pre-Cat Ox sensor, and start it up, see if it runs better (it'll be loud)

Common fault with 2.4 is clogged exhaust due to misfires, primary cat come apart and debris get caught at second cat and stop the exhaust flow,, may hear drone-roar out of air filter box too when try to accell hard
