Ive only ever had this issue in the winter until now. This morning I went to get coffee and when I cold started my car the first 4-5 seconds of startup were very uneven and rough if that makes sense. The car shook and vibrated allot and then this died down once the revs went down. Later in the day I went to start my car, the car made the nice usual startup pops and crackles and as i went to slightly blip the throttle the car stuttered and completely died. I turned the car back on and everything seemed normal. This has happened one or two times before in the exact same context but was in sub freezing temps. My only thought is bad gas but I go to the same station everytime I fillup with 93 and the only other times this issue has happened was 5 states away with different gas. Anyone experiencing similar issues or might know what this could be?
