Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, multimeter, flashlight.
Disconnect the battery to ensure safety during inspection and repair.

2. Repair Exhaust System

Inspect and Repair Leaks:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Use a flashlight to inspect the exhaust system for cracks, holes, or loose fittings.
3. Tighten any loose clamps or connections.
4. If leaks are found, use exhaust repair tape or replace damaged sections with new components.

3. Replace Spark Plugs and Ignition Coils

Remove and Replace:
1. Remove the engine cover if applicable.
2. Disconnect the ignition coil connectors and unbolt the coils.
3. Remove the old spark plugs using a spark plug socket and ratchet.
4. Install new spark plugs (ensure proper gap according to specifications).
5. Reinstall ignition coils, ensuring they are securely bolted and connected.

4. Check and Repair Intake System

Inspect and Replace Components:
1. Remove the air intake duct to access the intake manifold.
2. Inspect for cracks or leaks in the intake manifold and vacuum hoses.
3. Replace any damaged hoses or components.
4. Reassemble the intake system and ensure all clamps are tight.

5. Fuel System Testing

Check Fuel Pressure:
1. Connect the fuel pressure gauge to the fuel rail.
2. Turn the ignition to the ON position (do not start) to check pressure readings.
3. If pressure is below specifications, inspect the fuel pump and filter for blockage or failure.
4. Replace any faulty components as necessary.
