Hey gang, I have a 2011 Cascadia with a DD15. It's been coding here lately with SPN 4364 fail 18. Had it in Clarke Power Services in Charlotte 3 times. Replaced both Nox sensors, doser valve and fuel meter. Keeps coding, but it only does it when I'm pulling a grade. It'll lose a little power, check engine light comes on, and then the malfunction indicator light comes on. As long as the check engine light is on, it won't pull that great. When it goes out, the truck pulls again. Anybody have any ideas as to what could be the problem?
