Hello, it's Brandy!  When I run, run, run, I don't hesitate, but have you ever felt your vehicle hesitate, go, then hesitate again? You might think there's something wrong with the transmission.  After all, it's not moving smoothly down the road.  But plenty of malfunctions can cause those symptoms, including one you may have never heard of: the EGR valve.  So today we will bark about the EGR valve and it's importance.  Let's get barkin'!!!

EGR stands for Exhaust Gas Recirculation. It channels small amounts of exhaust back into the engine to cool the cylinders and reduce polluting gases.  These include nitrogen oxides that can cause smog. The EGR valve regulates how much exhaust gas the vehicle recirculates. After years and long distances traveled, that valve can get clogged or fail. Sometimes the EGR valve can stick open.  When the EGR valve isn't working properly, your vehicle can start releasing nitrogen oxides and polluting the air.

The symptoms of a malfunctioning EGR valve include:

• Engine losing power
• Engine idling roughly
• Pinging and knocking sounds in the engine
• Stalling and hesitation
• Fuel economy decreasing
• Check Engine light illuminated

Depending on its condition, the EGR valve can be cleaned, or it may need to be replaced.  Consult with your service advisor to see what options are recommended to you.

The EGR system is part of your vehicle's pollution and emissions control equipment. If you care about keeping our planet's atmosphere clean, make sure it's doing its job—for everyone's benefit.

I leave you with this classic proverb,

 “Fresh air is good for the soul.”
