I just bought this car. It ran fine for a couple of days but now it seems to have an issue when I try to step on the gas from a complete stop. There is a hesitation. It dogs for a second or two then everything is fine again until I get to the next stop. Would this be a sensor issue or possibly a fuel filter issue? Thanks.
