Focus 2003 Stalling problem
Hi I'm new here. I have been having a stalling problem with my 2003 Ford Focus ZTS. When idling at a stop light or stop sign the engine will start to run rough and sometimes cut out and stall. It does not do this while moving only when at a stop. I have been to two mechanics and they have not been able to identify the problem. I have had the oxygen sensors replaced already also a fuel pump to no avail.

Otherwise we love the heated seats!

Any suggestions would be appreciated!

Try cleaning the mass air flow sensor, and if that doesn't work its time to replace your idle air control valve.

Check your PVC hose, too. The passenger end where it bends sharply can split and/or get soft and collapse, and ruin the idle.
