I have my EGR installed but I cant pass emissions. I have extremely high NOx and this engine has less than 3000 miles on it. Just wondering if the EGR can actually malfunction causing high NOx. If not, what other issues could be causing this? :ugh2:

Yep, that can happen. Have you tried taking off the pipes and cleaning them out? I've done this on my 3cyl Sprint 3 times now because my NOx was too high. Worked every time though!
