Rough idle, Higher RPM surge

Car has slight miss at idle, when running down the highway it will intermitantly get a surge in the way it runs. I think it is one of two problems. One I may need new injectors(havent had time or weather good enough to Ohm out).Or a problem with the evap system. Car seems to puke out gas when tank is full and has a strong gas smell when parked sometimes.Havent really had time to look at it yet, but I figured some one out there may have had a simular problem and could possibly tell me where to start, Thanks
