Exhaust gas recirculation valves, or EGR valves, redirect hot exhaust gases back into your engine's intake
manifold. EGR valves cut emissions and enhance engine efficiency; a failed EGR valve will result in a rough
idle, loss of power, poor fuel economy and a trouble code that illuminates the Check Engine light. The good news
is that an EGR valve is simple to replace -- shop Advance Auto Parts for EGR valves from top brands like
ACDelco, Intermotor, BWD and Motorcraft.
The EGR valve is one of the earlier efforts at reducing emissions, dating back to the mid-70s. EGR valves
redirect a portion of exhaust gases back into the cylinders to be burned again, which cuts nitrogen oxide
emissions and helps reduce peak temperatures inside the combustion chambers.
The EGR valve can get fouled by carbon and no longer cycle on and off (it depends on coolant temperature for
its operation), resulting in a trouble code, Check Engine light, poor fuel economy and a tendency to surge
and stumble at part throttle. Don't put up with drivability problems - shop Advance Auto Parts for a
valve kit. Read More
