Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety if working on electrical components.

2. Replace Air Filter

Locate the air filter housing and open it.
Remove the old air filter and clean the housing.
Install the new air filter, ensuring it fits snugly.
Reassemble the housing and reconnect any clips or screws.

3. Clean Fuel Injectors

Remove the fuel injectors from the fuel rail.
Use a fuel injector cleaning kit or ultrasonic cleaner to clean the injectors.
Reinstall the cleaned injectors, ensuring O-rings are in good condition and properly seated.

4. Repair or Replace Exhaust Components

Inspect the exhaust system for cracks or holes, particularly in the manifold and catalytic converter.
If leaks are detected, replace the affected components.
Ensure all connections are secure and check for proper sealing.

5. Replace Fuel Filter (if applicable)

Locate the fuel filter, usually along the fuel line.
Relieve fuel system pressure before removal.
Remove the old fuel filter and install the new one, ensuring correct orientation.
