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.

2. Inspect and Replace Fuel Filter

Locate the fuel filter, typically along the fuel line.
Use a socket set to remove the fuel filter from the line.
Install a new fuel filter, ensuring proper orientation and tight connections.
Reconnect the battery and check for leaks by turning the ignition to the "On" position without starting the engine.

3. Clean or Replace Air Filter

Open the hood and locate the air filter housing.
Remove the air filter cover using a screwdriver or socket set.
Take out the air filter and inspect it for dirt and blockage.
Clean the filter with compressed air or replace it with a new one.
Reassemble the air filter housing securely.

4. Inspect and Test Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector from the TPS.
Use a multimeter to check the resistance and voltage output while moving the throttle plate.
If values are out of specification, replace the TPS with a new sensor.
Reconnect the connector and ensure it is secure.

5. Check and Replace Spark Plugs

Remove the ignition coils by unscrewing them using a socket wrench.
Take out the spark plugs with a spark plug socket.
Inspect the spark plugs for wear or fouling; replace them if necessary.
Reinstall new spark plugs with the correct gap and torque specifications.
Reattach ignition coils securely.
