it wount respond whei presss the gas on 2003 Ford Crown Victoria


my vehicle suffered from same problem, stalled while engine was still called and attempted to shut down when I pressed down on accelerator pedal. I thoroughly cleaned the Map sensor( with map sensor cleaner only or it will be damaged) I also removed and cleaned the Egr valve assembly. Vehicle runs like a 2010 model. Hope this helps, pretty sure it will. It helped me.
