Default Check engine code 71, sputtering when cold

So I cleaned out my EGR valve and the little filter as well. I got loads of buildup out of the valve, too. I then pulled the fuse.

Check engine light came back on with the same code and the car sputters a bit when the engine is cold. After a few minutes, the car warms up and it goes away.

Kinda worried since I have an e-test tomorrow morning :S

Well I passed my e-test with flying colors.

The problem persists...

Yeah, I read about it and considered it...

Not sold on it working though.
