What's up guys I have a 2001 Ford Focus ZX3 that stalls whenever my car is at an idle whether it's in drive or Park once it is warmed up. I have replaced the EGR valve the idle air control valve the PCV valve and the hose that smooshes shut that goes to the PCV. The engine light is not on and have checked to see if there's codes showing up theres none. PLEASE HELP ME!!!
