Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool before beginning work.

2. Replace Air Filter

Tools Required: Flathead screwdriver, new air filter
Remove the air intake duct by loosening the clamps with a screwdriver.
Take out the old air filter and clean the airbox with a vacuum or cloth.
Install the new air filter, ensuring it fits snugly into the airbox.
Reattach the air intake duct and secure the clamps.

3. Check and Replace Spark Plugs

Tools Required: Socket set, torque wrench, spark plug socket
Remove the ignition coil connectors and unscrew the coils.
Using the spark plug socket, carefully remove the old spark plugs.
Inspect the spark plugs for wear and replace them if necessary (recommended gap: 0.044 inches).
Install new spark plugs and tighten to the manufacturer's torque specification (typically 13-15 lb-ft).
Reinstall the ignition coils and connectors.

4. Inspect and Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver
Disconnect the throttle body electrical connector and intake hose.
Remove the throttle body from the intake manifold by unscrewing it.
Clean the throttle plate and bore using throttle body cleaner and a soft cloth.
Reinstall the throttle body and reconnect the electrical harness and intake hose.

5. Fuel System Inspection

Tools Required: Fuel pressure gauge, line wrench
Attach the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start the engine) to check the fuel pressure.
If pressure is below manufacturer specifications, consider replacing the fuel filter or fuel pump.
If replacing the fuel pump, remove the rear seat or access panel, disconnect the fuel lines, and unscrew the pump assembly.
