Hey guys, On my way home I got this check engine code P1415 The car wanted to stall waiting at a red light when it happened but then it was normal but once I turn on my A/C it constantly does it. Anyone have a clue what it could be? Google says it can be a vacuum hose or something but anyone else have an opinion on this? Thanks!
