My EGR valve went bad again:facepalm:. Fortunately the part is under warranty. If not Crank shaft pos sensor, it is EGR valve is faulting. 2 bad Crankshaft position sensors from NAPA and 1 bad EGR valve from Autozone so far. I am not sure if these two problems related. How often does EGR valve go bad? Any ideas?:confused:
