I already knew that my EGR was having some issues, I could feel it. But, recently, the Check Engine/ SES light has come on, giving me code 32 (EGR). I picked up a new one, and finally replaced it yesterday (along with finally installing my Taylor Spiro-Pro wires).
My passages were pretty clean, as I re-did the top end just over a year ago. The old EGR valve also moved easily by hand. The biggest difference between the two is the damping action as the valve opens and closes. I suppose this makes sense; if the old valve opened quickly, it could cause a lean condition and stumble, especially when cold. The new valve opens & closes much more slowly, and the running results definitely show that. Smoother throttle from a stop, and no more of the feeling that the mixture is changing while driving.

It's the standard replacement from Autozone!
