Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the battery to prevent any electrical issues during repair.

2. Replace Air Filter

Locate the air filter housing.
Remove the screws or clips securing the housing.
Take out the old air filter and clean the housing with a damp cloth.
Install the new air filter, ensuring it fits snugly.

3. Clean Fuel Injectors

Remove the fuel rail assembly from the engine.
Disconnect the fuel lines carefully using a line wrench.
Use a fuel injector cleaning kit and follow the manufacturer’s instructions to clean the injectors.
Reinstall the fuel rail and ensure all connections are tight.

4. Replace Spark Plugs

Remove the ignition coil covers if applicable.
Disconnect the ignition coils and remove them using a socket set.
Unscrew the old spark plugs using a spark plug socket and inspect them for wear.
Install new spark plugs, applying the manufacturer-recommended torque (typically 13-15 ft-lbs).
Reconnect the ignition coils and covers.

5. Test Fuel Pressure

Attach the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine to check for initial pressure readings.
Start the engine and observe the pressure; it should fall within the manufacturer's specifications (typically 30-60 psi for most models).
