engine light came on; car surges while stopped at a light. on 2007 Hyundai Entourage

Live in Las Vegas, NV. Very hot weather right now but I have never had my engine light come on. I always make sure I tighten the gas cap after filling up. Also, while stopped at a red light my car would like surge forward so I put it in neutral now while stopped.
