When you press the gas while moving it wants to bog down but then goes back to normal for a second then does it again over and over seems like its not getting enough gas or its missing.

Okay i dont have a Catalytic converter, and i just got the Cap and rotor replaced. And it acts up only when your driving but not when parked, and the longer it runs, the check engine light will come on for a little bit not for very long though, then goes off.
