Yesterday both my check engine and ESP lights clicked on. I just put a new Carbonio intake in my car and im wondering if that could have caused my check engine to pop on. Also while im driving when i let off the gas pedal my intake makes a little blow off sound im just wondering if thats normal for it because this is my first car that is turbo'ed. The ESP light is probably something i'll have to take in to get checked out though unless someone has an idea?
