Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to ensure safety during repair.

2. Replace Air Filter

Remove the air filter housing by unscrewing the retaining screws.
Carefully take out the old air filter.
Install a new air filter, ensuring it is seated properly.
Reattach the air filter housing and secure it with screws.

3. Inspect and Replace Spark Plugs

Remove the ignition coil(s) by unscrewing them from the engine.
Disconnect the electrical connector from each coil.
Unscrew and remove the old spark plugs using a spark plug socket.
Check the gap on the new spark plugs and adjust if necessary.
Install new spark plugs, tightening them to the manufacturer’s specification (usually 15-20 Nm).
Reinstall the ignition coils.

4. Clean or Replace Fuel Injectors

If fuel injectors are clogged, use a fuel injector cleaning kit to clean them.
If replacement is needed, disconnect the fuel lines and electrical connectors from the injectors.
Remove the old injectors from the fuel rail and install new ones.
Reconnect fuel lines and connectors, ensuring no leaks are present.

5. Test Throttle Position Sensor

Disconnect the TPS connector and test the sensor with a multimeter.
Measure the voltage while moving the throttle; it should change smoothly.
If faulty, replace the TPS by unscrewing it from the throttle body and installing a new one.
