Solution

1. Preparation

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

2. Inspect and Replace Ignition Components

Sub-steps:
1. Remove the engine cover (if applicable) using a socket set.
2. Disconnect the ignition coils from the spark plugs.
3. Remove the old spark plugs using a spark plug socket and inspect for wear.
4. Install new spark plugs, ensuring to use the manufacturer's recommended type and torque them to specification (usually around 20 Nm).
5. Replace any damaged ignition coils and reconnect them securely.

3. Check Fuel System

Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Connect the fuel pressure gauge to the test port.
3. Turn the ignition on (do not start the engine) and check the fuel pressure; it should be within manufacturer's specifications (usually around 50-60 psi).
4. If pressure is low, inspect the fuel pump, fuel filter, and fuel lines for blockages or failures.
5. Replace the fuel filter if clogged and verify the fuel pump operation.

4. Clean and Inspect Air Intake System

Sub-steps:
1. Disconnect the air intake duct from the throttle body.
2. Inspect the air filter and replace it if dirty or clogged.
3. Clean the throttle body with throttle body cleaner and a soft cloth.
4. Reassemble the air intake system, ensuring all connections are tight.
