Problems:
Oil leaks
Common in older Ford Focus models, may result from worn-out gaskets or seals.
Timing belt failure
In-Line 4-cylinder engines often have timing belts that can wear out and snap if not replaced at recommended intervals.
Overheating
Can be caused by a failing water pump, clogged radiator, or a malfunctioning thermostat.
Ignition coil failure
Can lead to misfires and poor engine performance, particularly common in early 2000s Ford models.
Pzev components
Partial Zero Emission Vehicle (PZEV) components such as the evaporative emissions system can fail, leading to increased emissions and failed emissions tests.
Fuel pump issues
Can lead to engine stalling or failure to start, more common as the vehicle ages.
Egr valve problems
Exhaust Gas Recirculation (EGR) valve may clog or fail, causing rough idling and reduced fuel efficiency.
