Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface with the engine off.
Tools Required: OBD-II scanner, fuel pressure gauge, multimeter, socket set, cleaning supplies.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Clean the Throttle Body

Remove the throttle body from the intake manifold.
Use throttle body cleaner and a soft cloth to clean the interior surfaces, removing any carbon deposits.
Reinstall the throttle body and ensure all connections are secure.

3. Replace Spark Plugs

Remove the ignition coils from the spark plugs.
Using a socket set, unscrew and remove the old spark plugs.
Install new spark plugs, ensuring they are gapped correctly according to specifications.
Reattach the ignition coils and ensure they are seated properly.

4. Check and Replace the Fuel Filter

Locate the fuel filter based on the vehicle's 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 and replace the old filter with a new one.
Reconnect fuel lines securely and reinstall the fuel pump fuse.

5. Inspect and Replace the Air Filter

Open the air intake housing and remove the air filter.
Inspect the filter for dirt and debris. Replace it with a new air filter if it is clogged.
Reassemble the air intake housing.
