My 91 civic pulsates when you go over 55 and sometimes it is not getting fuel somewhere because when you press on the gas nothing but if you wait a second it will start going again the engine does not shut off it just doesn't get enough gas somewhere now yesterday the check engine light came on I have changed the fuel filter tune up what can be the problem
