Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the engine is cool before starting work.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner onto a clean cloth and wipe the inside of the throttle body to remove carbon deposits.
Reattach the air intake duct securely.

3. Replace the Air Filter

Locate the air filter housing and unclip or unscrew it to access the air filter.
Remove the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits snugly in the housing.
Reassemble the air filter housing.

4. Test the Fuel Pressure

Connect a fuel pressure gauge to the fuel rail's test port.
Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading against manufacturer specifications.
If pressure is low, check for a faulty fuel pump or clogged fuel filter.

5. Inspect Accelerator Pedal Position Sensor

Locate the accelerator pedal assembly and disconnect the electrical connector.
Use a multimeter to test the resistance of the sensor while slowly pressing the pedal.
Replace the sensor if readings are inconsistent or outside manufacturer specifications.
