Frequent Problems in the Ford Focus
When the warning light comes on in a Ford Focus, you are most likely facing one of these chronic issues:
- DPF saturation or dirty EGR valve, very typical if you do a lot of city driving.
- Misfires (coils or spark plugs), causing jerking and the P0300 code.
- Dirty or faulty oxygen sensors (Lambda probe), which increase fuel consumption.
