Potential causes include worn ignition parts (coils and spark plugs), lean condition (too much air, vacuum leak), rich condition (too much fuel, fuel presser, leaking injector) or a worn engine (carbon buildup or low compression).
Can a bad gas cap make your car run bad?
As the gas cap is removed every time the vehicle is refueled, it will often wear out simply due to repeated use. While a faulty gas cap will not necessarily cause major performance issues, it can cause the vehicle to experience fuel and emission problems.

Why does my car run rough After fueling up?
Possibly at one time the tank got topped off, which caused fuel to be sucked into the evap canister at one time.
