Helpful Information
An EGR valve also helps cool combustion temperatures to stem engine detonation or pinging while the engine is under load. The operation of the valve begins while engine vacuum is lowered due to throttle position and declines as maximum vacuum returns (idle.) Carbon can build up along the valve passages so occasional maintenance is recommended.
