Every once in a while when i stop at a stop sign or light my car kinda sputters and acts like it wants to die, what could possibly be wrong?

Do you have a check engine light on? If so you need to start by getting it scanned. Many things can cause the symptoms you are describing. An engine misfire, vacuum leak, bad throttle position sensor, issue with throttle body or front o2 sensors. Bad fuel pump, faulty spark plugs and motor and trans mounts can cause it to shake as well. This type of issue is going to require a hands on inspection by a pro. Here is a link you can use to find a shop near you. https://repairpal.com/repair-shops Alex
