What is the engine vacuum at idle?
Can I start by getting your VIN?

Your going to have to start by checking for air/vacuum leaks and checking the fuel system. Be sure no fuel is leaking into the engine with it off or running. You can check this using a fuel pressure gauge hooked up with the key on engine off. If everything checks out good, the most common cause for these codes is either bad oxygen sensors or sticky valves or valve springs. You can check for a base engine mechanical problem using a hand held vacuum gauge at idle. The needle should be nice and steady and should not fluctuate with the engine at idle. If so, that indicates a base engine mechanical problem.
Hello! YES, the EGR alve can go bad affecting these things. However, my experience has been if the EGR valve is bad causing these conditions, it would set an EGR code.
The P0406 is a very common code on this vehicle. 9 times out of 10, this is caused by a bad EGR valve provided the wiring are in good shape.
The P0113 is for the air intake temp sensor. This is usually just a bad sensor causing this code.
I think it is related to the valves causing the engine to misfire. I would check engine vacuum like I mentioned earlier. If that checks out good, then yes, I would replace the EGR valve.
