EGR Flow Test Using O2 Sensor was created by Tutti57
Section 4 page 10. It says that EGR command during cruising would make O2 Rich.

I'm pretty sure opening the EGR at idle kills the engine, I thought from leaning it out. Does it make a difference if it's opened during idle vs cruising?

I have a note that put in my book on that page indicating that this is only true on a speed density engine.

If i wrote it in the book, it must have been addressed by Paul in a premium video.

Gotcha. Increased manifold pressure making ECM think it's a load?
