Hello
First off, what is the squell from? Belt? Possibly your alt is locking up.
I don't think the EGR valve will cause the engine to quit. The ports that lead to your EGR valve may be pluged with carbon giving you the EGR error. These trouble codes just point to the trouble. It doesn't always mean that the device is bad.
Any think else happening? Lights dimming?
