I have a 2000 honda accord ex. And sometimes when im at a light and it turns green i was press the gas and the car speedometer would go crazy. I would press the gas to go and and it wouldn't start to go smoothly but as im driving it works fine. I just have problem when I start car and I would press the gas and take a couple seconds to go as im pressing the gas and it would go eventually. Whats wrong with my car? Could it be the Fuel Pump?
