Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a flat surface, and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Fuel System Components

Inspect the fuel filter:
- Locate the fuel filter (refer to the service manual for specific location).
- Remove any mounting clips or fasteners.
- Disconnect fuel lines carefully to avoid spillage.
- Replace with a new fuel filter if clogged or damaged.
Check the fuel pump:
- Access the fuel pump (may require removing the fuel tank or accessing through the rear seat).
- Test the pump operation using a fuel pressure gauge.
- Replace the fuel pump if pressure is below specifications.

3. Inspect and Replace Ignition System Components

Check spark plugs:
- Remove spark plug wires and unscrew the spark plugs using a socket wrench.
- Inspect for wear, carbon buildup, or damage.
- Replace with new spark plugs if necessary, ensuring they are gapped correctly according to specifications.
Examine ignition coils:
- Remove the ignition coil from the engine (may need to disconnect wiring harness).
- Test each coil with a multimeter to check for proper resistance.
- Replace any faulty coils.

4. Inspect Air Intake System

Check the air filter:
- Open the air filter box and remove the air filter.
- Inspect for dirt and debris; replace if necessary.
Inspect intake hoses:
- Look for cracks or leaks in the intake hoses.
- Replace any damaged hoses to ensure proper airflow.
