Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.
Allow the engine to cool before starting the work.

2. Air Filter Replacement

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect for dirt and debris.
Install a new air filter, ensuring it is seated properly.
Reassemble the air filter housing cover and tighten the screws to the manufacturer’s specifications.

3. Fuel System Check and Repair

Attach the fuel pressure gauge to the fuel rail service port.
Turn the ignition on (do not start the engine) and check the pressure reading.
- If pressure is below specification, replace the fuel pump.
If the pump is operational, check the fuel filter for clogs and replace if necessary.

4. Ignition System Inspection

Remove spark plug wires or ignition coils based on the engine configuration.
Inspect and clean or replace spark plugs if fouled or worn.
Test ignition coils with a multimeter to ensure they meet resistance specifications; replace if faulty.

5. Throttle Body Cleaning

Disconnect the throttle body from the intake manifold.
Use a throttle body cleaner and a soft brush to clean carbon deposits from the throttle plate and housing.
Reinstall the throttle body, ensuring all gaskets are in good condition and replace if necessary.
