Hey, can anyone tell me what an EGR valve actually does? Also, is it just one of those parts that goes bad, or do you have to do somthing to it for it not to work?

thanks.

The EGR valve meters a portion of the exhaust, since its inert, back into the intake system to reduce peak combustion temperatures which in turn limits the formation of oxides of nitrogen. Reducing the the peak combustion temperatures also helps to reduce pinging. Since the valve meters exhaust, it can accumulate exhaust deposits that can hinder it's smooth operation.
