Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to prevent electrical shorts.
  • Ensure the vehicle is on a level surface and use wheel chocks for safety.
2. Inspect and Replace Air Filter
  • Remove the air filter housing cover using a screwdriver.
  • Take out the old air filter and inspect it for dirt and damage.
  • Install a new, clean air filter, ensuring it is seated properly.
  • Reattach the air filter housing cover securely.
3. Fuel System Inspection
  • Attach a fuel pressure gauge to the fuel rail.
  • Start the engine and monitor the fuel pressure; it should meet specifications (refer to the service manual).
  • If pressure is low, check the fuel pump, fuel filter, and fuel lines for clogs or leaks.
  • Replace any faulty components as necessary.
4. Spark Plug Inspection and Replacement
  • Remove the ignition coil packs using a socket set.
  • Extract the spark plugs using a spark plug socket.
  • Inspect each spark plug for wear, carbon buildup, or damage.
  • Replace worn or fouled spark plugs with OEM or high-quality aftermarket parts.
  • Reinstall the ignition coils and ensure they are secured.
5. Throttle Body Cleaning
  • Remove the intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
  • Wipe away any residues with a clean cloth.
  • Reconnect the intake duct securely.
6. Reconnect Battery and Test
  • Reconnect the battery terminals.
  • Start the engine and allow it to idle for a few minutes.
  • Test drive the vehicle to check for improvements in acceleration.
