Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety.
Allow the engine to cool before proceeding.

2. Fuel System Inspection

Remove the fuel pump access panel if applicable or raise the vehicle safely.
Tools Required: Fuel pressure gauge, socket set, multimeter.
Connect the fuel pressure gauge to the fuel rail and start the engine.
Check the fuel pressure against manufacturer specifications (typically between 50-60 psi).
If pressure is low, replace the fuel pump.
- Sub-steps:
  - Disconnect the fuel lines and electrical connections.
  - Remove the fuel pump assembly.
  - Install the new fuel pump and reconnect connections.

3. Throttle Body Cleaning

Remove the air intake duct connected to the throttle body.
Tools Required: Screwdriver set, throttle body cleaner.
Spray throttle body cleaner onto a clean cloth and wipe the throttle body’s interior.
Ensure the throttle plate moves freely and is not stuck.
Reattach the air intake duct securely.

4. Ignition System Check

Remove the spark plugs for inspection.
Tools Required: Spark plug socket, gap gauge.
Inspect each spark plug for wear and proper gap (typically 0.040 inches).
Replace any damaged or worn spark plugs.
Reinstall the spark plugs and reconnect ignition coils.
