An extremely high temperature within the combustion chamber signifies some nitrogen oxide is formed which could pollute environmental surroundings. The Pontiac Sunfire EGR valve prevents the growth of NOX, commonly known as nitrogen oxides, within the chamber and prevents it from being discharged into the environment. In the 60's, the Exhaust Gas Recirculation commonly known as EGR system was initially released to the public so as to increase environmental consciousness.

A vacuum controlled valve routes a specific volume of exhaust back inside the combustion chamber of the motor. Smog and nitrogen oxides are lessened when exhaust levels are directed back into the the chamber. To aid in the combustion process, an EGR valve keeps the proper volume of air combination in the chamber. A plugged EGR valve may result to irregularities with the efficiency, such as valve knock and in certain situations, even rough idling. A bad valve will also reduce the speed of your car.
