i have a 1988 accord lx, 4 cylinder carb motor, and there are some times of the day that she will idle on her own, but most of the time she will struggle for a about a minute or so, and then just die, and whenever i put on the brakes in neutral; she dies. also, when i pump the brakes repeatedly, instead of kicking up the idle, it kills the engine. anyone got any ideas or suggestions?
