Everyone...thanks for the inputs. I went to the dealer who found a
bad EGR-type sensor. This had NOTHING to do with K&N and if you go
to their site they have in their FAQs that you can only damage an
air sensor if you oil the filter excessively. They have never had
an incident of their filters damaging sensors but that is a
common "rumor". THe light is off, K&N back in and the SuprCrew
is "haulin' butt" once again! Thanks again! -PJ
