What is causing my 2003 Focus to stall and run rough? (See details below)

  • 2003 FORD FOCUS
  • 140,000 MILES

I own a 2003 Ford Focus that has approx. 140K miles on it. Over the last 6 months I have had issues with the vehicle staying running. Meaning it tries to stall when at a low idle speed. It dies, 98% of the time when I turn the air conditioner on. If I hold the gas it stays running. I took it in to a car chain shop. They have replaced the plugs, wires, alternator, battery, water pump, and several other smaller parts that I am honestly not sure what they are at the moment. (I know I have been taken)Either way, any ideas what it may be? I have been reading on websites that keep mentioning coilpacks, if that may be it, is it something easy to replace? Where is it? Any help would be great. Thank You

Do you
have the same problem?

I would look at the pcv hose back at the throttle body for a leak causing all your issues.
