Fuel injector replacement is not a DIY job due to the risk of fire
A fuel injector is a component of a car engine that regulates the amount of pressurised fuel used for each engine cycle. There is one fuel injector per cylinder in an engine. When a fuel injector fails or clogs, engine power is reduced and misfires occur. The check engine light will turn on and, as the issue progresses, the engine may stall immediately after starting, fail to start, hesitate under throttle or vibrate roughly. It is unsafe to drive a vehicle with a fuel injector problem, as it can cause the car to stall or accelerate unpredictably, creating a hazard.
Fuel injectors tend to fail after 80,000 miles and require little maintenance. To prolong the life of the fuel injectors, it is recommended to follow the scheduled maintenance and cleaning routine. If fuel delivery system symptoms are present, a technician will first conduct a visual inspection. If the issue is unclear, the technician will connect a computerized scanner to the vehicle to read its sensors. If there is a fuel injector problem, the technician would likely find that misfires are happening frequently on one cylinder. The fuel injector or injectors in question must be tested and may require removal for bench testing. Any failed components must be replaced, and the vehicle will be checked to ensure the problem is fixed.
Typically, the intake manifold must be removed to access and replace the fuel injectors. This can be a large job that may involve draining the coolant and oil and removing many engine components. Some cars, however, are designed with plastic intake manifolds that do not have oil or coolant passages, making this process easier. Due to the complexity of this process, fuel injector replacement should be left to professionals.
The risk of fire is a significant concern when replacing fuel injectors. Additionally, this repair can get very complicated, and a good amount of knowledge is required to remove the injectors, intake manifold, fuel rail, and other components safely. If done incorrectly, it can cause further damage to the vehicle. The average cost for a Ford Focus Fuel Injector Replacement is between $450 and $503, but this can vary depending on the specific car model and location.

Fuel injectors regulate the amount of pressurised fuel used for each engine cycle
The Ford Focus is a car model that has been in production since 1998. While I cannot confirm the number of fuel injectors in a Ford Focus, I can confirm that fuel injectors are used to regulate the amount of pressurised fuel used for each engine cycle.
Fuel injection is the process of introducing fuel into an internal combustion engine through a fuel injector. This process is used in both compression-ignition engines (diesel engines) and spark-ignition engines (petrol engines). The fuel injector is an electronically-controlled valve that, when energised, uses an electromagnet to move a plunger, which opens the valve and allows pressurised fuel to squirt out through a tiny nozzle. This nozzle is designed to atomise the fuel, creating a fine mist that can be easily burned.
The amount of fuel supplied to the engine is determined by the length of time the fuel injector stays open, known as the pulse width. This is controlled by the Engine Control Unit (ECU), which uses sensors to monitor the mass of air entering the engine and the amount of oxygen in the exhaust to fine-tune fuel consumption and delivery. The ECU ensures that the air-to-fuel ratio is optimal, and it can adjust this ratio in real-time through closed-loop control, which was not feasible with carburettors.
The introduction of fuel injection systems allowed for stricter emissions requirements to be met, as catalytic converters required careful control of the air-to-fuel ratio to function effectively. Fuel injection also offers advantages in terms of "driveability", providing easy starting, smooth running, and no engine stuttering.
In terms of the specific number of fuel injectors in a Ford Focus, online forums dedicated to Ford Focus owners and enthusiasts suggest that a set of four fuel injectors is compatible with the Ford Focus models from 2008 to 2011.

Signs of a failing fuel injector include poor fuel economy, engine hesitation, and unusual sounds
The Ford Focus is a popular car model that has been in production since the early 2000s. While the design and specifications of the fuel injection system may vary depending on the year and model of the Ford Focus, it is common knowledge that fuel injectors play a crucial role in the engine's performance and fuel efficiency. Typically, a Ford Focus is equipped with four fuel injectors.
Now, let's delve into the signs that indicate failing fuel injectors, including poor fuel economy, engine hesitation, and unusual sounds.
Poor Fuel Economy: One of the most common signs of a failing fuel injector is a decrease in fuel economy. This occurs when the injectors are restricted or clogged, leading to an imbalance in the fuel-air mixture. As a result, the engine may consume more fuel than usual to maintain its performance, causing a drop in miles per gallon.
Engine Hesitation: Engine hesitation or stumbling during acceleration is another symptom of faulty fuel injectors. This happens when the injectors fail to deliver the precise amount of fuel required by the engine, resulting in a lack of power and hesitation when you try to accelerate. In some cases, this may be accompanied by unusual sounds, such as sputtering or rough idling.
Unusual Sounds: Unusual sounds, such as excessive engine vibration or a "bucking bronco" sensation, can indicate that your fuel injectors are not functioning properly. This is often caused by engine misfires due to a lack of fuel in the cylinders, leading to an uneven or incomplete combustion process.
Other signs of failing fuel injectors include increased difficulty in starting the engine, poor engine performance, and the illumination of the ""Check Engine" light on your dashboard, which could indicate a problem with the fuel injector or another issue that requires immediate attention.
It is important to note that while these are common signs of failing fuel injectors, there could be other underlying causes. Therefore, it is always recommended to consult a qualified mechanic for a thorough diagnosis and appropriate repairs.
