Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Air Intake System

Remove the air intake duct and inspect for debris or blockages.
Clean the air filter; replace if damaged or excessively dirty.
Reattach the air intake duct securely.

3. Check and Replace Fuel Filter

Locate the fuel filter under the vehicle or in the engine bay.
Use a fuel line disconnect tool to detach the fuel lines from the filter.
Install a new fuel filter, ensuring correct orientation and secure connections.

4. Examine and Replace Ignition Components

Remove spark plug wires and inspect for damage or corrosion.
Use a spark plug socket to remove the spark plugs; check for wear and replace if necessary.
Inspect ignition coils for proper function and replace any faulty coils.

5. Test and Replace Throttle Position Sensor

Disconnect the electrical connector from the throttle position sensor.
Use a multimeter to check the resistance; replace the sensor if readings are out of specification.
Reconnect the new sensor ensuring a secure fit.

6. Inspect Catalytic Converter

Visually inspect the catalytic converter for physical damage or signs of blockage.
If necessary, remove the catalytic converter and perform a back-pressure test.
Replace the catalytic converter if it fails the test.
