Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool before working on the vehicle.

2. Replace Clogged Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and dispose of it.
Install a new air filter, ensuring it fits snugly.
Reattach the air filter housing cover and secure it.

3. Fuel Pressure Check and Repair

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position without starting the engine to check pressure; it should be within specifications.
If pressure is low, inspect and replace the fuel pump or fuel filter as needed.
Disconnect the fuel line and replace the fuel filter if it is clogged.

4. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket set.
Take out the old spark plugs using a spark plug socket.
Inspect the spark plugs for wear; replace if they show signs of damage or excessive wear.
Install new spark plugs with the proper gap settings and torque them to manufacturer specifications.
Reinstall the ignition coils.

5. Throttle Position Sensor Adjustment

Locate the throttle position sensor.
Disconnect the electrical connector and remove the screws holding it in place.
Install a new throttle position sensor if necessary, ensuring it is correctly aligned.
Reconnect the electrical connector.
