Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Address Fuel System Issues

Fuel Pump Inspection:
- Remove the rear seat or trunk cover to access the fuel pump.
- Disconnect the electrical connector and fuel lines carefully.
- Test the fuel pump with a multimeter to ensure it is functioning (specific voltage as per service manual).
- If faulty, replace the fuel pump with a new assembly.

3. Clean the Throttle Body

Throttle Body Access:
- Remove the air intake duct connected to the throttle body.
- Disconnect the throttle position sensor connector.
Cleaning Process:
- Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
- Ensure all carbon deposits are removed while avoiding damage to the butterfly valve.
Reassembly:
- Reconnect the throttle position sensor connector and air intake duct.
- Ensure all clamps are tight and secure.

4. Replace Engine Coolant Temperature Sensor (if necessary)

Sensor Location:
- Locate the engine coolant temperature sensor (usually near the thermostat housing).
Replacement Steps:
- Disconnect the electrical connector from the sensor.
- Unscrew the old sensor using a socket wrench.
- Apply thread sealant to the new sensor and install it, tightening to the specified torque.
- Reconnect the electrical connector.

5. Final Steps

Reconnect the battery.
Start the engine and allow it to idle to check for any irregularities.
