Solution

1. Preparation

Gather tools and ensure you are in a well-ventilated area.
Disconnect the battery to prevent electrical shorts.

2. Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft brush, rags.
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner onto the throttle plate while opening it manually to clean any residue.
Wipe clean with a soft rag and reassemble the air intake duct.

3. Inspect and Replace the Accelerator Pedal Position Sensor

Tools Required: Multimeter, socket set.
Locate the accelerator pedal position sensor and disconnect the electrical connector.
Use a multimeter to check for voltage at the sensor terminals; refer to manufacturer specifications.
If the sensor is faulty, remove it by unscrewing the mounting bolts and install a new sensor, reconnecting the electrical connector.

4. Fuel System Check

Tools Required: Fuel pressure gauge, socket set.
Locate the fuel rail and connect the fuel pressure gauge to the test port.
Turn the ignition to the "ON" position (do not start the engine) to check fuel pressure. Compare the reading to manufacturer specifications.
If pressure is low, inspect the fuel pump and filter, replacing them as necessary.
