Solution

1. Preparation

Gather tools and materials, including an OBD-II scanner, socket set, fuel pressure gauge, and replacement parts as needed.
Ensure the vehicle is on a flat surface and the engine is cool before starting repairs.

2. Addressing Fault Codes

If error codes are present, look up the specific codes to determine the root cause.
Clear the codes and conduct a road test to see if they reappear.

3. Replace Air Filter

Remove the air intake cover using a socket set.
Take out the old air filter and install a new one, ensuring it fits snugly.
Reattach the air intake cover and secure it with the original fasteners.

4. Fuel System Service

Disconnect the fuel pump relay to relieve fuel pressure.
Use a fuel pressure gauge to check fuel pressure; if low, replace the fuel pump.
Clean or replace the fuel injectors using a cleaning kit or the injector replacement method.

5. Spark Plug and Ignition Coil Replacement

Disconnect the battery to prevent electrical shorts.
Remove the engine cover (if applicable).
Unplug the ignition coils and remove them using a socket set.
Replace spark plugs using a spark plug socket, ensuring they are gapped correctly according to specifications.
Reinstall ignition coils and reconnect the battery.
