Notice the conditions when it happens. Is the car warm or cold? Is the weather warm or cold? Does it only happen at idle? You get the picture. If you can correlate a situation that exists every time you have this problem, you are close to solving the problem.
Makes me think of how bad my fuel pump may be. I have replaced my fuel filter already.
