Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off and keys removed.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Throttle Position Sensor

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and remove the sensor using the appropriate socket.
Install the new throttle position sensor, ensuring it is seated properly.
Reconnect the electrical connector.

3. Clean or Replace Air Filter

Open the air filter housing by removing the screws or clips.
Remove the air filter and inspect it for dirt and blockages.
If dirty, clean it using compressed air or replace it with a new air filter.
Reassemble the air filter housing.

4. Test and Replace Fuel Pump if Necessary

Attach the fuel pressure gauge to the fuel rail.
Turn the ignition key to the "ON" position without starting the engine and check the fuel pressure.
If the pressure is below manufacturer specifications, replace the fuel pump.
To replace, remove the fuel tank access cover, disconnect the fuel lines, and unbolt the pump assembly. Install the new pump and reconnect all components.

5. Inspect and Replace Ignition Components

Remove the engine cover to access the ignition coils.
Disconnect the electrical connectors from the coils and remove them using a socket.
Inspect spark plugs for wear and replace them if necessary.
Install new ignition coils, ensuring they are securely fastened and connectors are reattached.
