If the gap between the electrode and the plug increases your fuel economy will go down but the actual driving manners of the car will not change by much.

I want you to think as to why the car would do this. Your engine is running yet the car is not moving (0 MPG) so yeah letting your car idle for extended periods of time will kill your overall MPG reading. You should only let a car run for maybe twenty seconds (less if it is warm outside) before putting it into gear and taking off down the road.
