think i'm going to delete my egr today, have spacers to make up for it. i read that it will make my truck ping, or can. what are the odds of it happening? its a 76 360 4x4 with auto. 2bbl motorcraft carb. the egr probably doesn't work and in my eyes is just a waste of space considering its emissons and will clean up the engine and make 2 less vacuum lines that i need to worry about. got rid of the rest of the ac lines today and one of the exhaust maifold.
