Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrench set, safety glasses.
Sub-steps:
1. Locate the fuel pump relay and remove it.
2. Connect the fuel pressure gauge to the fuel rail.
3. Turn the ignition key to the "ON" position (do not start the engine) to check the fuel pressure.
4. Compare the reading to the specifications in the service manual (typically around 40-50 psi).
5. If the pressure is low, inspect the fuel pump for proper operation and replace if necessary.

3. Ignition System Service

Tools Required: Socket set, torque wrench, spark plug socket.
Sub-steps:
1. Remove the ignition coils from the engine.
2. Inspect the spark plugs for wear or damage; replace if necessary.
3. Torque the new spark plugs to the manufacturer’s specification (typically 13 ft-lbs).
4. Reinstall ignition coils and ensure connections are secure.

4. Air Intake and Vacuum Leak Inspection

Tools Required: Vacuum gauge, hose clamp pliers.
Sub-steps:
1. Inspect the air filter and replace it if dirty.
2. Use a vacuum gauge to check for vacuum leaks by connecting it to a vacuum source on the intake manifold.
3. If a leak is detected, inspect hoses, gaskets, and intake manifold for cracks or disconnections.
4. Replace any damaged components to restore proper vacuum levels.
