Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, multimeter.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative terminal of the battery for safety.

2. Addressing Error Codes

Use the OBD-II scanner to retrieve and document any error codes.
Clear the codes and take the vehicle for a test drive to see if any new codes appear.

3. Air Intake Inspection

Remove the air intake duct to access the air filter.
Inspect and replace the air filter if dirty or clogged.
Check for any cracks or loose connections in the intake ducting.

4. Fuel System Repair

Connect the fuel pressure gauge to the fuel rail.
Start the engine and check the fuel pressure against manufacturer specifications (typically 30-60 psi for F-150).
If pressure is low, inspect the fuel pump and replace if defective; if normal, check for clogged fuel injectors and clean or replace as necessary.

5. Ignition System Service

Remove the spark plugs using a socket set and inspect them for wear or fouling.
Replace any damaged spark plugs and check ignition coils for proper operation using a multimeter.
Reinstall spark plugs with the correct torque specification (typically 12-15 lb-ft).

6. Exhaust System Inspection

Visually inspect the exhaust system for visible damage or blockages.
If applicable, check the catalytic converter for signs of restriction or failure.
Replace any damaged components.
