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 shorts.

2. Inspect the Fuel System

Sub-step 1: Locate the fuel pump access panel (if applicable) or remove the rear seat to access the fuel pump.
Sub-step 2: Attach a fuel pressure gauge to the fuel rail and turn the ignition on without starting the engine.
Sub-step 3: Check the fuel pressure reading against the manufacturer's specifications (typically around 50-60 psi).
Sub-step 4: If the pressure is low, replace the fuel pump and filter as necessary.

3. Clean the Throttle Body

Sub-step 1: Remove the intake air duct connected to the throttle body using a socket set.
Sub-step 2: Disconnect the electrical connector from the throttle body.
Sub-step 3: Use throttle body cleaner and a soft brush to clean the throttle plate and the bore.
Sub-step 4: Reassemble the throttle body and reconnect the air duct.

4. Replace Ignition Components

Sub-step 1: Remove the ignition coil cover using a socket set.
Sub-step 2: Disconnect the electrical connector from each ignition coil.
Sub-step 3: Remove the ignition coils and spark plugs.
Sub-step 4: Replace the spark plugs with new ones according to specifications.
Sub-step 5: Reinstall the ignition coils and reconnect the electrical connectors.

5. Reconnect Battery

Reconnect the negative terminal of the battery.
Start the engine and monitor for any abnormal sounds or check engine light indications.
