- Locate the air filter housing and open it.
- Remove the old air filter and inspect it for dirt or damage.
- Install a new air filter if necessary.
Tools Required: Flathead screwdriver or Torx driver (depending on the housing type).

3. Clean Throttle Body

Sub-steps:
- Remove the intake duct connected to the throttle body.
- Use throttle body cleaner and a soft cloth to clean the throttle plate and interior of the throttle body.
- Reconnect the intake duct securely.
Tools Required: Socket set, throttle body cleaner, soft cloth.

4. Check and Replace Spark Plugs

Sub-steps:
- Remove the ignition coils by unscrewing them from the cylinder head.
- Use a spark plug socket to remove old spark plugs and inspect them for wear.
- Install new spark plugs, ensuring they are gapped correctly to manufacturer specifications.
- Reinstall the ignition coils and torque them to the specified value.
Tools Required: Spark plug socket, torque wrench.
Safety Warnings: Ensure the engine is cool to prevent burns.

5. Inspect Fuel System

Sub-steps:
- Connect a fuel pressure gauge to the fuel rail and turn the ignition on to check pressure.
- If pressure is low, inspect the fuel pump and fuel filter for issues.
- Replace fuel filter if necessary and, if the fuel pump is faulty, replace it.
