Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reattach the air intake duct securely.

3. Check and Replace Spark Plugs

Remove the ignition coils by unscrewing them and pulling them out gently.
Use a spark plug socket to remove the spark plugs from the engine.
Inspect the spark plugs for wear or carbon buildup; replace if necessary with the manufacturer-recommended type.
Reinstall the spark plugs and ignition coils, ensuring they are torqued to the manufacturer's specifications.

4. Inspect and Test Fuel System

Connect a fuel pressure gauge to the fuel rail to check for proper fuel pressure as specified by Ford.
If pressure is low, check the fuel pump operation and replace it if faulty.
Inspect fuel injectors for clogs or malfunction; clean or replace if needed.

5. Inspect MAF Sensor

Locate the mass airflow sensor in the intake system.
Disconnect the electrical connector and remove the sensor.
Clean the sensor with MAF cleaner and reinstall it, ensuring a secure connection.
