Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool before working on intake or engine components.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Use a throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Ensure that no cleaner enters the intake manifold.
Reinstall the air intake duct and tighten to the manufacturer's torque specification.

3. Check Fuel Pressure

Locate the fuel pressure test port on the fuel rail.
Connect a fuel pressure gauge to the test port.
Start the engine and observe the fuel pressure reading; it should meet specifications.
If pressure is low, inspect the fuel pump and fuel filter for issues.

4. Inspect Spark Plugs

Remove the ignition coils by unbolting them and disconnecting the electrical connectors.
Take out the spark plugs using a spark plug socket and inspect for wear or fouling.
Replace any faulty spark plugs with OEM specifications and torque to the manufacturer’s values.

5. Test Accelerator Pedal Position Sensor

Disconnect the electrical connector from the accelerator pedal position sensor.
Use a multimeter to check the resistance values according to the service manual specifications.
If out of range, replace the sensor and reconnect.
