Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fuel Filter

Sub-steps:
1. Locate the fuel filter (typically near the fuel tank).
2. Use a wrench to disconnect the fuel lines (be cautious of residual fuel).
3. Remove the old fuel filter and install the new one.
4. Reconnect the fuel lines securely.
5. Reconnect the battery.

3. Check and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if necessary.
2. Disconnect the ignition coils from the spark plugs.
3. Use a spark plug socket to remove the old spark plugs.
4. Inspect the old plugs for wear; replace them with new ones if necessary.
5. Reinstall the coils and the engine cover.

4. Clean or Replace Mass Air Flow Sensor (MAF)

Sub-steps:
1. Locate the MAF sensor in the air intake duct.
2. Disconnect the electrical connector.
3. Remove the MAF sensor using a screwdriver.
4. Clean the sensor with MAF cleaner or replace it if cleaning does not resolve issues.
5. Reinstall the sensor and reconnect the electrical connector.

5. Inspect and Repair Vacuum Leaks

Sub-steps:
1. Visually inspect all vacuum hoses for cracks or disconnections.
2. Use a smoke machine or carburetor cleaner to identify leaks.
3. Replace any damaged hoses or components.
4. Test the system after repairs to ensure no leaks remain.
