Cleaning a Subaru Electronic EGR Valve to Smooth Rough Idle and Improve Power.

A dirty EGR valve can rob horsepower and cause unstable idle issues and acceleration issues. By cleaning the EGR valve, you can assure that the emissions system is working correctly and not leaking unwanted exhaust gasses into the intake at the wrong time. This is a pretty simple procedure that you can do at home. This EGR valve is on a 2013 Subaru Legacy and is an all electronic valve. Many older cars feature a vacuum operated EGR valve that can rip over time, causing a leak or failure to actuate. Cleaning your EGR valve is a simple way to restore horsepower. The exact procedure in this video is applicable to a 2012, 2013, 2014, or 2015 Subaru Legacy and Subaru Outback. The procedure will be very similar on most modern cars.
