Chances are you have a fuel injector that is stuck open, or the fuel pressure regulator is leaking. I would remove the vacuum line from the regulator and see if fuel is present, if so, the part is bad and needs replacement. If that is okay remove the spark plugs to see if any are flat black, this will be the cylinder the injector needs to be replaced at. Please go over this guide as well:
