After removing all EGR harware, installing Weeks I and II, and re-flashing ECM back to Nick's stock flash (it was F37) I started getting complaints from the MAF sensor. It is clean and looks fine, but the MAP sensor was so crusty that even brake cleaner and aggressive scrubbing won't clean it out fully. Ordered a replacement, hopefully that rectifies the CEL. However, has anyone found any other sensors that can be affected by excessive crud buildup in the intake? I was shocked that it was that dirty after only 63,000 miles. The entire intake needs to come off and be run through a parts cleaner. Nasty.
