Ok guys, my check engine light has been coming on for a while now saying my egr valve is bad! Iv already bought the new part! But what exactly is the valve for? And does it hurt my fuel mileage and horsepower?? The weird thing is that the check engine light stays on all the time but will sometimes go off on it's own but will soon return! I did have the bully dog triple gt tuner on for about a year it made my o2 sencer go bad an the light would stay on! But I took the tuner off and now it just shows the egr!
