Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to ensure safety while working on electrical components.

2. Replace Air Filter

• Locate the air filter housing, usually positioned near the engine.
• Remove the clips or screws holding the air filter cover in place.
• Take out the old air filter and dispose of it properly.
• Install the new air filter, ensuring it is seated correctly.
• Reattach the air filter cover and secure it with clips or screws.

3. Clean or Replace Fuel Injectors

• Access the fuel injectors by removing the engine cover and any necessary components.
• If cleaning, use a fuel injector cleaning kit per the manufacturer's instructions.
• If replacing, detach the fuel rail, remove old injectors, and install new ones, ensuring O-rings are lubricated and seated correctly.
• Reattach the fuel rail, ensuring all connections are secure.

4. Replace Spark Plugs

• Remove the ignition coils by unscrewing the bolts and disconnecting the electrical connectors.
• Unscrew the old spark plugs using a socket wrench.
• Inspect the old plugs for wear; if they are fouled or worn, replace them with new ones, using the recommended gap settings.
• Reinstall ignition coils and secure them.

5. Inspect and Repair Exhaust System

• Visually inspect the exhaust system for any visible leaks or loose connections.
• Use an exhaust gas analyzer to check for excess emissions.
• Repair or replace any damaged components, such as the catalytic converter or muffler, as needed.
