Solution

1. Preparation

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

2. Inspect and Replace Spark Plugs

Remove the ignition coil cover if applicable.
Disconnect the electrical connectors from the ignition coils.
Use a socket set to remove the spark plugs.
Inspect for wear, carbon buildup, or damage and replace if necessary with OEM specifications.
Reinstall the spark plugs and ignition coils, ensuring they are torqued to the manufacturer's specifications.

3. Check and Replace Fuel Filter

Locate the fuel filter in the fuel line.
Use appropriate wrenches to remove the filter; prepare for fuel spillage.
Install the new fuel filter, ensuring correct orientation and tightness.

4. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
Reassemble the air intake duct securely.

5. Test Fuel Pressure

Connect the fuel pressure gauge to the fuel rail test port.
Start the engine and observe the fuel pressure reading; it should match the manufacturer’s specifications.
If pressure is low, consider replacing the fuel pump.

6. Final Assembly

Reconnect the battery.
Ensure all components are properly secured and no tools are left in the engine bay.
