EGR is Exhaust Gas Recirculation - it is an emissions control device that uses the hot exhaust gas to warm up your engine faster. A warm modern engine produces practically zero emissions with proper cats, etc.
Clogged EGR valves make the engine run rough, and may impact fuel economy so I'm sure it did make a difference.

There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
