Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working.
Allow the engine to cool completely before starting work.

2. Inspect and Replace Spark Plugs

Sub-steps:
- Remove the ignition coils by unscrewing the retaining bolts and pulling them out.
- Use a spark plug socket to remove the spark plugs.
- Inspect the old spark plugs for signs of fouling or wear.
- Install new spark plugs, ensuring they are gapped correctly (typically 0.028-0.032 inches for Ford engines).
- Reinstall the ignition coils and secure them with the retaining bolts.
Tools required: Spark plug socket, torque wrench, ratchet, feeler gauge.

3. Fuel Injector Inspection and Cleaning

Sub-steps:
- Disconnect the fuel lines and electrical connectors from the injectors.
- Remove the fuel rail to access the injectors.
- Inspect each injector for clogs and clean them using an appropriate injector cleaning solution and tool, or replace if necessary.
- Reassemble the fuel rail and reconnect the fuel lines and electrical connectors.
Tools required: Fuel line disconnect tool, injector cleaning kit.

4. Check and Fix Air Intake System

Sub-steps:
- Inspect the air filter for clogs and replace if dirty.
- Check for any vacuum leaks in the intake manifold and hoses.
- Ensure all clamps and connections are tight.
Tools required: Screwdrivers, pliers.

5. Exhaust System Inspection

Sub-steps:
- Visually inspect the exhaust manifold, pipes, and connections for cracks or loose fittings.
- Use an exhaust leak detector if necessary to identify any leaks.
- Repair or replace damaged sections as needed.
Tools required: Wrench set, exhaust leak detector.
