I was driving back home from work yesterday and some idiot was going under the speed limit on the left lane. I got pissed off and floored it to go around him and all of a sudden I get the Engine Malfunction reduced power warning. I immediately take the next exit find a spot to park and shut off the car. I waited a couple minutes and restarted the car and there is no problem and all the warnings are gone. I got home and checked for error codes and I got these:

30FC exhaust fume turbo charger, density
2DC3 control clamp 15
2E8D Intelligent battery sensor, signal transmission

The car is completely stock. It was probably the 30FC that put the car in limp mode but I have no idea what caused it. I checked all the boost lines and visually they all seem fine. Any input would be appreciated.
