And that is the thing, the CEL is and has been gone since that day. Hasn't came back. But the car is running the same inconsistency as the few hours it was on that night, terrible. Does anyone know if that is maybe a soft code or have any reason why it would have went away on it's own overnight?! So now I have no CEL and a bad running, and bad idling car with nowhere to look besides an EGT Probe as far as I know. Would a bad EGT Probe make my car run like this?! I was told that the EGT probe does nothing but measure the temp in the UP/voltage in sensor and if it is not within a certain window, you get the orange light of death in your gauge cluster. So if that is the case and I am getting credible info, that would make my car run like that would it?! I have more probs?

CEL's can come and go if the condition that caused them subsides. As you saw, they do often remain in memory though, but not always. It depends on the code. The UP EGT is pretty much like you described. It's only purpose is to ensure the UP cat doesn't get overheated. I've heard stories of cat material and even the EGT probe itself getting sucked right into the turbo.
Remove the intake, reset the ECU, and see how it runs and if any CEL's return.
