So I was driving along and all of a sudden my SES light comes on. (I have the stock h-pipe) Then I came home, reset the battery and started the car, and no more SES light. What was this all about? I almost thought it was my Magnapacks causing the computer to throw a code because of the reduced backpressure on a stock engine. Should I take it to the dealer the next time it comes on? Could this be the aftermath of my 40 mph rear-end collision? (The car is fixed now but the body shop could've half-assed something)
