Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt or damage.
Install a new air filter, ensuring it fits securely into the housing.
Reattach the air filter housing cover and tighten it.

3. Fuel System Pressure Check

Connect a fuel pressure gauge to the fuel rail's test port.
Turn the ignition to the "ON" position without starting the engine and check the pressure reading.
If pressure is low, check the fuel pump and fuel filter for proper operation and replace them if necessary.

4. Throttle Body Cleaning

Remove the air intake duct attached to the throttle body.
Use throttle body cleaner and a clean cloth to wipe down the interior of the throttle body, removing carbon deposits.
Reattach the air intake duct securely.

5. Spark Plug Inspection and Replacement

Remove the ignition coils by unscrewing them with a socket set.
Take out the spark plugs using a spark plug socket and inspect them for wear or fouling.
Replace with new spark plugs that meet manufacturer specifications.
Reinstall the ignition coils.
