Solution

1. Preparation

Gather tools and materials. Ensure the engine is cool before starting.
Tools required: OBD-II scanner, socket set, multimeter, vacuum gauge.

2. Retrieve and Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve stored error codes and take note of any related to the engine or fuel system.
Clear the codes and test drive the vehicle to see if they reappear.

3. Inspect and Replace Idle Air Control Valve (if faulty)

Locate the idle air control valve, typically near the throttle body.
Disconnect the electrical connector and remove the mounting screws.
Inspect the valve for carbon buildup and clean if necessary; if damaged, replace with a new valve.
Reinstall the valve and reconnect the electrical connector.

4. Check and Replace Throttle Position Sensor (if faulty)

Locate the throttle position sensor on the throttle body.
Disconnect the sensor connector and remove it from the throttle body.
Use a multimeter to test the sensor's resistance and voltage output.
If out of specifications, replace the sensor and reconnect.

5. Assess Fuel System

Inspect the fuel pump operation by checking fuel pressure with a gauge.
Replace the fuel filter if it appears clogged or has not been changed per service intervals.
If the fuel pump is faulty, replace it and ensure proper operation by checking fuel delivery and pressure.

6. Final Assembly and Testing

Reconnect any components that were removed during inspection.
Start the vehicle and allow it to idle, checking for smooth operation and any signs of stalling.
Test drive the vehicle to confirm the repair was successful.
