Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative terminal of the battery to avoid electrical issues during repairs.

2. Inspect and Clean the Idle Air Control Valve

Tools Required: Socket set, cleaning solvent, soft brush
Remove the intake manifold cover, if applicable.
Locate the idle air control valve (IAC).
Disconnect the electrical connector and remove the IAC from the throttle body.
Clean the IAC using a cleaning solvent and a soft brush.
Reinstall the IAC and reconnect the electrical connector.

3. Fuel System Inspection

Tools Required: Fuel pressure gauge, line wrenches
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Connect the fuel pressure gauge to the fuel line.
Turn the ignition to the "ON" position (without starting) and check the fuel pressure reading against manufacturer specifications.
If the pressure is low, inspect the fuel pump and filter for issues, replacing as necessary.

4. Throttle Body Cleaning

Tools Required: Socket set, cleaning solvent, soft cloth
Remove the air intake duct from the throttle body.
Inspect the throttle body for carbon buildup.
Clean the throttle body using a cleaning solvent and a soft cloth.
Reassemble the intake duct securely.

5. Final Assembly and Testing

Reconnect the negative terminal of the battery.
Start the engine and allow it to idle.
Verify that there is no stalling when the vehicle comes to a stop.
