I have a '91' ford aerostar sport with a 3.0 engine it was driving fine and all of a sudden it started idling funny and if I didnt keep the gas pedal pressed or if I hit the brakes it would stall out I have changed the spark plugs, spark plug wires ,distributar cap, roter button,Oc sensor, and the idle air control sensor but it still does the same thing I have also checked the fuel filter and fuel flow and they seem to be good I dont know what else to check if you have any ideas please let me know thanks.
