Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, cleaning supplies.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Clean the Throttle Body

Remove the intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner on a clean cloth and wipe the throttle body interior to remove carbon deposits.
Reinstall the intake duct, ensuring a proper seal.

3. Replace the Fuel Filter

Locate the fuel filter according to the service manual.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using the appropriate tool.
Install the new fuel filter, ensuring that the flow direction is correct.
Reconnect the fuel pump fuse and check for leaks.

4. Clean or Replace the MAF Sensor

Disconnect the MAF sensor connector.
Remove the MAF sensor from its housing.
Use MAF sensor cleaner to clean the sensor elements carefully.
Reinstall the sensor and connector.

5. Inspect and Replace Ignition Components

Remove the ignition coils and inspect the spark plugs for wear or damage.
Replace worn spark plugs with new ones, ensuring the gap is set to manufacturer specifications.
Reinstall the ignition coils, tightening to the specified torque.
