EGR- exhaust Gas Recirculation. Basically when you let off the throttle it causes and large vacuum in the intake. At the same time the exhaust has the most of its pollutant being emitted. The EGR valve, at the rear of the intake, opens and allows exhaust gasses to run back through the intake system. It doesn't help the mixture of fuel and air at this point, so less power when you get back on the gas. I just unbolted mine and filled the hole with JB Weld and put it back on. You could make a block off plate to go there instead. You also have to pinch off the tube that runs into the intake. The emissions will go up slightly so not sure if you would pass inspection. Here in Louisiana they don't seem to be concerned about that but the change is so small that in the big picture it doesn't bother me, probably to Green Peace it does though.
