Solution

1. Preparation

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

2. Air Intake Inspection

Sub-steps:
1. Remove the air filter cover using a socket set.
2. Inspect the air filter for dirt and replace it if necessary.
3. Check the intake ducts for cracks or loose connections.
Tools Required: Socket set, flashlight.

3. Fuel System Check

Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Turn the ignition to the ON position (without starting the engine) and check the pressure readings.
3. If pressure is below specifications, inspect the fuel pump and replace if faulty.
Tools Required: Fuel pressure gauge.

4. Throttle Body Cleaning

Sub-steps:
1. Remove the intake duct connected to the throttle body.
2. Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
3. Reinstall the intake duct securely.
Tools Required: Throttle body cleaner, soft cloth.

5. Ignition System Inspection

Sub-steps:
1. Remove spark plug wires and inspect for wear or damage.
