Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shock.

2. Replace Air Filter

• Remove the air filter housing cover using a screwdriver.
• Take out the old air filter and clean any debris from the housing.
• Install the new air filter, ensuring it is seated correctly.
• Reattach the air filter housing cover and secure it.

3. Fuel System Inspection

• Connect a fuel pressure gauge to the fuel rail.
• Start the engine and observe the fuel pressure reading; it should be within the manufacturer's specifications.
• If pressure is low, check the fuel pump and fuel filter for issues, replacing them if necessary.

4. Spark Plug Replacement

• Remove the ignition coil or spark plug wires carefully.
• Unscrew the spark plugs using a socket wrench.
• Inspect the old plugs for wear; replace with new ones if necessary, ensuring the gap is set to manufacturer specifications.
• Reinstall the ignition coils or spark plug wires.

5. Throttle Body Cleaning

• Remove the air intake duct connected to the throttle body.
• Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding housing.
• Reattach the air intake duct securely.

6. Exhaust System Inspection

• Visually inspect the exhaust system for any visible damage or blockages.
• If blockages are found, remove and clean or replace affected sections of the exhaust.
