Solution

1. Preparation

Gather tools and parts required for repair.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery to prevent electrical shock.

2. Clean or Replace the Throttle Body

Tools Required: Screwdriver set, throttle body cleaner, rags.
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner to spray the throttle body and clean any carbon deposits.
Reinstall the air intake duct securely.

3. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench.
Remove the ignition coil connectors and unbolt the coils.
Remove the old spark plugs using a spark plug socket.
Inspect for wear; replace with OEM or equivalent spark plugs if worn.
Torque the new spark plugs to manufacturer specifications (typically around 13-15 lb-ft).
Reinstall the ignition coils and connectors.

4. Fuel System Check

Tools Required: Fuel pressure gauge.
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition key to the 'ON' position (do not start) and check the fuel pressure (should be within manufacturer specifications).
If pressure is low, consider replacing the fuel pump or checking the fuel filter for clogs.
