I HAVE JUST NOTICED THAT MY CAR IS JERKING A LITTLE BUT JUST TODAY I NOTICED IT IDLING WIERD. AS I STOPPING AT A RED LIGHT I NOTICED BEGINNING TO JERK AND WHEN I STEPPED ON THE GAS IT WAS JERKING A LITTLE AT ANOTHER RED LIGHT I HAD MY FOOT ON THE BRAKE AND THE CAR BEGAN TO IDLE PAST THE 1 AND BACK DOWN AND UP AGAIN. I HAVE ALSO SEEN IT TODAY AT 20-25 MPH IDLING PAST THE 3. NO CHECK ENGINE LIGHT HAS GONE ON. WHAT SHOULD I DO? WHAT COULD IT BE?

First, if there is no light, then the computer hasn't picked up on the problem yet. So, you need to start by checking for vacuum leaks.

Let me know if you find any. Also, the problem could be caused by a few things, but without the light, anything I say would be a guess.
