Why does your 2002 mountaineer stall out on idle and at stop lights but not when the vehicle is being driven?

# Idle speed incorrect # Fuel filter clogged and/or water and impurities in fuel system # Damaged or wet distributor cap and wires # Emissions system components faulty # Faulty or incorrectly gapped spark plugs my 2002 mountaineer did the same thing and it was a crack vaccum line.
