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 during repairs.

2. Air Intake System Inspection

Remove the air intake duct to access the air filter.
Inspect and replace the air filter if dirty; clean the intake duct if necessary.
Reconnect the air intake duct securely.

3. Fuel System Repair

If fuel pressure is low, replace the fuel filter and inspect the fuel pump.
Ensure fuel lines are not kinked or damaged.
If necessary, replace the fuel pump and ensure proper connection and sealing.

4. Ignition System Service

Remove the ignition coils and spark plugs.
Inspect spark plugs for wear; replace if they show signs of damage or excessive wear.
Reinstall new or cleaned ignition coils, ensuring proper torque specifications are followed (typically 7-10 Nm).

5. Throttle Body Cleaning

Remove the throttle body from the intake manifold.
Clean the throttle body using throttle body cleaner and a soft brush.
Reinstall the throttle body, ensuring all gaskets are in good condition and properly seated.

6. Battery and Charging System Check

Test the battery voltage with a multimeter; replace the battery if voltage is below 12.4V.
Check the alternator output; replace if not within the range of 13.5V to 14.5V under load.
