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.

Clean out the idle air control valve and EGR valve, also test the throttle position sensor and also clean the MAF sensor with an approved cleaner
