Solution

1. Preparation

Gather tools and parts needed for repairs.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Air Filter

Remove the air filter housing cover.
Take out the old air filter and inspect the housing for debris.
Install a new, clean air filter and reassemble the housing.
Tools Required: Screwdriver set, new air filter.

3. Fuel Pressure Test and Replacement

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the ON position (without starting the engine) to check the pressure reading.
If pressure is low, replace the fuel pump.
Tools Required: Fuel pressure gauge, socket set, new fuel pump.

4. Inspect and Replace Spark Plugs

Remove ignition coils to access spark plugs.
Carefully pull out the old spark plugs using a spark plug socket.
Inspect the old spark plugs for damage and replace with new ones if necessary.
Reinstall ignition coils.
Tools Required: Spark plug socket, torque wrench, new spark plugs.

5. Check and Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner to clean the interior of the throttle body.
Reinstall the air intake duct securely.
Tools Required: Throttle body cleaner, screwdriver set.

6. Exhaust System Inspection

Visually inspect the exhaust system for any signs of damage or blockages.
If the catalytic converter is clogged, replace it.
Tools Required: Socket set, new catalytic converter (if needed).
