at 198K brake line failed while parked at work, fluid drained out into parking lot  
today, at 201K it is running OK, but shutters accellerating, idles OK, hold constant speed OK, but at any speed, from 10 to 70mph it shutters if I accellerate 'mildly' have full power when I punched it briefly into passing gear, but shutters afterward trying to gently accel.

P0304 is a misfire on Cylinder #4. Time to replace the plug, I'd do all of them. See if that helps, if not then replace the coil on that cylinder.
