93 Octane

problem

when accelerating the car jerks/bucks when there are pops/bangs under acceleration which is not normal. While logging this it caused an EPC code and misfire. This is the first time it misfired. I shut car off and cleared the code and it has not come back, although I'm afraid to push it hard to make the misfire come back. Usually it just pops/jerks under acceleration in most gears. The harder I accelerate the worse it is. But if I don't accelerate hard the car runs and idles normal with no check engine lights.
