Solution

1. Preparation

Gather tools and ensure a clean workspace.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Air Intake Issues

Air Filter Replacement:
- Locate the air filter housing.
- Remove the housing cover using a socket set.
- Replace the old air filter with a new one, ensuring a snug fit.
Throttle Body Cleaning:
- Remove the intake duct connected to the throttle body.
- Spray throttle body cleaner onto a clean rag and wipe the throttle plate and inside the throttle body.
- Reassemble the intake duct and secure it properly.

3. Fuel System Repair

Fuel Filter Replacement:
- Locate the fuel filter (consult the service manual for exact location).
- Depressurize the fuel system by removing the fuel pump fuse and starting the engine until it stalls.
- Disconnect fuel lines from the filter using appropriate tools, ensuring to capture any spilled fuel.
- Replace the fuel filter with a new one and reconnect the fuel lines securely.

4. Ignition System Maintenance

Spark Plug Replacement:
- Remove the ignition coil cover if applicable.
- Disconnect the ignition coils and remove them using a socket set.
- Use a spark plug socket to remove old spark plugs and replace them with new ones, ensuring the correct gap is set (consult specifications).
- Reinstall the ignition coils and cover.

5. Exhaust System Inspection

Exhaust Leak Repair:
- Visually inspect the exhaust system for any visible damage or rust.
- Use an exhaust leak detector if necessary to pinpoint leaks.
- Replace any damaged sections of the exhaust pipe or gaskets.
