Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool if it has been running.

2. Addressing the Throttle Body

Remove the air intake duct connected to the throttle body.
Use a throttle body cleaner to clean the throttle plate and surrounding area.
Reinstall the air intake duct securely.
Reconnect the battery.

3. Inspecting the Ignition System

Remove the spark plug covers (if applicable) using a socket set.
Inspect each spark plug for wear or damage; replace as necessary.
Check ignition coils for proper function; replace faulty coils.
Reinstall spark plugs and covers, tightening to manufacturer's torque specifications.

4. Fuel System Inspection

Locate the fuel pump access panel (if applicable) or remove the rear seat as necessary.
Test the fuel pressure using a fuel pressure gauge; compare readings to manufacturer specifications.
Replace the fuel filter if clogged or if the fuel pump is not providing adequate pressure.
