Ok, so I replaced the timing belt, water pump, crank seal, cam seal, alternator, alt belt, ac belt, oil changed, valve cover gasket and grommets and my car is sputtering like crazy, I put fuel injector cleaner in it and turned it on for about an hour and still sputtering. I mean it didn't turn on before so im not complaining. I just need the sputtering gone. Any suggestions? Anyone have this problem?

Also, it needs a muffler but It's not that. You can feel it in the engine, like in some instances it like wants to turn off almost.
