Is your car idling rough? Have you noticed other engine irregularities such as valve knocks or uneven acceleration? Your EGR valve could be to blame. Short for exhaust gas recirculation, the EGR cools and streamlines the engine's combustion process. A faulty or malfunctioning EGR will reduce performance, shorten the lifespan of your vehicle, and could also prevent your vehicle from passing emissions control regulations. EGR repair is much more economical than replacement, so the time to deal with this brewing problem is now. Schedule an appointment today.
