Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent any electrical issues during the repair process.

2. Inspect and Replace Air Filter

Remove the air intake cover by unscrewing any fasteners.
Take out the old air filter and inspect it for dirt and clogs.
Replace with a new air filter that meets OEM specifications.
Reattach the air intake cover securely.

3. Check and Replace Spark Plugs

Remove the ignition coil from the spark plug assembly (using a socket set).
Unscrew the old spark plugs using a spark plug socket.
Inspect the spark plugs for wear, carbon buildup, or damage.
Install new spark plugs, ensuring the gap is set according to manufacturer specifications.
Reinstall ignition coils and secure them in place.

4. Clean Throttle Body

Remove the air intake duct leading to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and interior surfaces.
Ensure that the throttle plate moves freely and is not sticking.
Reattach the air intake duct securely.

5. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition key to the "on" position (do not start the engine) and check the fuel pressure reading.
If pressure is below the specified range, inspect the fuel pump and fuel filter for failures.
