Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, compression tester, fuel pressure gauge.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Repair Faulty Components

a. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and install a new one, ensuring a proper seal.
Reattach the air filter housing cover and secure it.

b. Replace Fuel Filter

Locate the fuel filter (refer to the owner's manual for specific location).
Relieve fuel pressure from the system by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using appropriate wrenches.
Install the new fuel filter, ensuring proper orientation, and reconnect the fuel lines.

3. Clean or Replace Catalytic Converter

If exhaust blockage is confirmed, remove the catalytic converter by unbolting it from the exhaust system.
Inspect it for any internal damage; if damaged, replace with a new catalytic converter.
If not damaged, clean it using a catalytic converter cleaner according to the product instructions.

4. Adjust or Replace Throttle Position Sensor

Disconnect the battery to prevent electrical shorts.
Locate the throttle position sensor on the throttle body.
Unplug the connector and remove the retaining screws. Replace with a new sensor.
Reconnect the battery and clear any OBD-II codes.
