Solution

1. Preparation

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

2. Inspect and Replace Fuel Filter

Sub-steps:
1. Locate the fuel filter (typically along the fuel line).
2. Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
3. Disconnect the fuel lines from the filter, using caution as fuel may spill.
4. Remove the old fuel filter and install the new one, ensuring the flow direction is correct.
5. Reconnect the fuel lines securely.

3. Check and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if necessary to access the spark plugs.
2. Disconnect the ignition coil connectors.
3. Use a socket wrench to remove the spark plugs.
4. Inspect the old spark plugs for signs of wear or fouling.
5. Install new spark plugs with the recommended gap (check vehicle specifications).
6. Reconnect the ignition coil connectors and replace the engine cover.

4. Clean or Replace MAF Sensor

Sub-steps:
1. Locate the MAF sensor in the air intake system.
2. Disconnect the electrical connector.
3. Remove the sensor from the intake tube.
4. Clean the sensor with MAF cleaner (do not touch the sensor elements).
5. Reinstall the sensor and reconnect the electrical connector.
