Solution

1. Preparation

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

2. Replace Fuel Filter

Locate the fuel filter (refer to the owner's manual for specific location).
Use a socket set to remove the old fuel filter, ensuring to have a catch pan for any spilled fuel.
Install the new fuel filter, securing it with the appropriate torque specifications.
Reconnect fuel lines and double-check for leaks.

3. Inspect and Clean Air Intake System

Remove the air intake duct by loosening the clamps and disconnecting the MAF sensor.
Inspect and clean the air filter; replace it if it is dirty or damaged.
Clean the MAF sensor using MAF cleaner, ensuring not to touch the sensor element.
Reassemble the air intake duct securely.

4. Test and Replace Ignition Components

Remove the ignition coils and inspect for cracks or corrosion.
Replace any faulty coils and check spark plugs for wear.
If necessary, replace spark plugs with the manufacturer-recommended type and torque them to specification.

5. Inspect and Replace Throttle Position Sensor (if necessary)

Locate the TPS on the throttle body.
Disconnect the electrical connector and remove the mounting screws.
Install the new TPS, ensuring it aligns correctly with the throttle body.
Reconnect the electrical connector.
