Just a little heads up here to lower the heart rate once in awhile. Running at the speedway this weekend and got a check engine light. See attached screen grab for a few. Opened the hood to find one of the stanless braided lines from the nitrous install (my doing) had abraided the insulation off one of the cam position adjusters at the front of the left hand cam and valve cover and was shorting to ground. Moved the stainless hose and taped up the abrasion but check engine light persisted and car a bit sluggish. Thinking all sorts of expensive things until it dawned on me that all those codes meant a circuit was bad, which led me to the fuse. #49 in the engine bay in my case. Phew.
