Answers for: "ford fiesta jerking"
Frequent Problems in the Ford Fiesta
If you have the check engine light on in your Ford Fiesta, it could be due to several common faults depending on whether it's a petrol engine (TSI, EcoBoost, VTi...) or diesel (TDI, TDCi, BlueHDi...):
- Problems with the EGR valve and the particulate filter (DPF) in diesel engines, causing power loss.
- Misfires (coils or spark plugs), causing jerking and the P0300 code.
- Dirty or faulty oxygen sensors (Lambda probe), which increase fuel consumption.
