Haha... Yeah, I debated putting that in there. I recently bought the ridgeline for a vehicle at the far away inlaws (saves on getting a rental car and we spend a lot of time there). The ridgeline has 200k miles on it. When I bought it, I did a crap ton of updating (all fluids, brakes, serpentine belt, PVC valve... including the cold air intake. Well, it had no CEL codes on it for one thousand miles and a month of driving. Then it threw the P0430 and P0420 codes. I freaked a bit and decided to bring it back to stock. Most folks have no issues with it, but I am going to let it go to be sure. I fear all my work may have 'shocked' the Ridgeline too much.
