Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety during repairs.

2. Addressing Fuel Pressure Issues

Check Fuel Pump Operation
- Connect the fuel pressure gauge to the fuel line.
- Turn the ignition to the "ON" position without starting the engine and observe the pressure reading. It should match manufacturer's specifications.
- If pressure is low, proceed to replace the fuel pump.
Replace Fuel Filter (if applicable)
- Locate the fuel filter; refer to the vehicle manual for the exact location.
- Use a socket set to disconnect the fuel lines from the filter and remove it.
- Install the new fuel filter, ensuring all connections are secure.

3. Inspecting the Throttle Body

Remove the Throttle Body
- Disconnect the electrical connector and the intake duct.
- Use a socket set to remove the mounting bolts and carefully detach the throttle body.
Clean the Throttle Body
- Use throttle body cleaner and a soft cloth to remove carbon buildup.
- Ensure the throttle plate moves freely after cleaning.
Reinstall the Throttle Body
- Reattach the throttle body, ensuring all bolts are torqued to the manufacturer’s specifications.
- Reconnect the electrical connector and intake duct.

4. Spark Plug and Ignition Coil Replacement

Remove Ignition Coils
- Disconnect the electrical connectors from the ignition coils.
- Use a socket set to remove the bolts securing the coils, then carefully pull them out.
Replace Spark Plugs
- Use a spark plug socket to remove old spark plugs.
- Install new spark plugs, ensuring they are torqued to the manufacturer’s specifications.
Reinstall Ignition Coils
- Reinstall the ignition coils and reconnect all electrical connectors.
