EGR Valves were developed as a way of reducing pollution. They reduce nitrogen oxide emissions, into the atmosphere, but it also reduces the performance of your vehicle as it introduces hot gases into the air intake. When the EGR valve goes bad or faulty, it must be replaced. A bad EGR valve can really affect the engine’s performance, or even cause it to stop running altogether.
