hello, i have a 2002 sunfire, and its doing something it never really did before. the car is running fine and everything, the check engine or service light do NOT come on or anything, never the less, since about a week ago, my car has been stalling only right before i take off and i dont really even give it that much gas, but once i let go of the gas and give it a little gas it goes fine. what could that be? iit kinda feels like the engine is not getting enough spark for the car to move. It also feels like something is clogged up thats causing the car to do this. It doesnt really seem like its an engine or transmition problems but cars are unpredictable so it could be anything. I really am not sure what this could be but if someone professional could help me i would really appreciate it. Thank you.
