Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft cloth, screwdriver set.
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner inside the throttle body and wipe with a soft cloth to remove carbon deposits.
Reattach the air intake duct securely.

3. Inspect and Replace Throttle Position Sensor (if necessary)

Tools Required: Multimeter, socket set.
Disconnect the electrical connector from the TPS.
Use a multimeter to check resistance and compare readings to specifications in the service manual.
If readings are out of spec, remove the TPS using a socket set and replace it with a new unit.
Reconnect the electrical connector.

4. Fuel Pump Inspection

Tools Required: Fuel pressure gauge.
Locate the fuel rail and connect the fuel pressure gauge.
Turn the ignition to the "ON" position without starting the engine and check the pressure reading.
If pressure is below manufacturer's specifications, replace the fuel pump as per service manual guidelines.

5. Accelerator Pedal Assembly Check

Tools Required: Socket set.
Remove the cover from the accelerator pedal assembly.
Inspect for any damaged or loose connections and repair or replace as necessary.
