EGR stands for Exhaust Gas Recirculation valve. This valve recirculated the unburnt gasses from the exhaust to be burnt by your engine.

No, the name is correct but the description is wrong. The EGR introduces exhaust into the combustion process to lower combustion temperatures which reduces detonation and pinging and reduces NOX gases.

How difficult is it to replace a drivers door glass in a 1990 Sentra. I am getting a replacement from a wrecker and was wondering if this was something that I could do myself. Any info is greatly appreciated.
