Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to avoid electrical shock.

2. Clean the Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reinstall the air intake duct ensuring all clamps are secured.

3. Replace Fuel Filter

Locate the fuel filter along the fuel line.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter using a line disconnect tool.
Remove the old fuel filter and install the new one, ensuring the flow direction is correct.
Reconnect the fuel lines and fuse, and check for leaks.

4. Inspect and Replace Ignition Components

Remove the ignition coils by unscrewing the mounting bolts and disconnecting the electrical connectors.
Remove and inspect spark plugs for wear; replace if necessary.
Install new spark plugs, ensuring the torque specification is met (typically 13-15 ft-lbs).
Reinstall ignition coils and connect the electrical connectors.

5. Test and Reset MAF Sensor

Disconnect the MAF sensor connector and inspect for debris or corrosion.
Clean the MAF sensor using MAF cleaner.
Reconnect the sensor and clear any fault codes using the OBD-II scanner.
