Why does my Ford Focus keep stalling?

Every time I come to a stop, my Ford Focus stalls out and I have to restart it. What could be causing this?

There could be a few possible reasons for this issue. One possibility is that there is a problem with your fuel system, such as a clogged fuel filter or a faulty fuel pump. Another possibility is an issue with your ignition system, such as worn spark plugs or a faulty ignition coil. It's also possible that there is an issue with your engine's idle control system. My advice would be to take your car to a trusted mechanic to diagnose the problem and get it fixed.

I had a similar issue with my Ford Focus and it turned out to be a problem with the throttle body. The throttle body was dirty and needed to be cleaned. Once it was cleaned, my car stopped stalling at stops. I would suggest checking your throttle body and cleaning it if necessary.

Another possibility is a faulty mass air flow sensor. This sensor helps regulate the air-to-fuel ratio in your engine and if it's not working properly, it can cause stalling issues. I would recommend having your mechanic check the mass air flow sensor and replace it if necessary.
