Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent any electrical short circuits.

2. Fuel System Inspection

Sub-step 1: Remove the fuel pump relay from the fuse box.
Sub-step 2: Connect a fuel pressure gauge to the fuel rail test port.
Sub-step 3: Have an assistant turn the ignition key to the "On" position (do not start the engine) to check if the fuel pressure meets specifications (typically between 50-60 psi for Volvo).
Sub-step 4: If pressure is low, inspect the fuel filter and fuel pump for clogs or failures.

3. Ignition System Repair

Sub-step 1: Remove the engine cover to access the ignition coils and spark plugs.
Sub-step 2: Inspect and replace worn spark plugs if necessary, ensuring they are gapped to specifications (typically 0.028-0.032 inches for Volvo).
Sub-step 3: Test each ignition coil with a multimeter for resistance and replace any faulty coils.
Sub-step 4: Reassemble the ignition components and reattach the engine cover.

4. Throttle Body Cleaning

Sub-step 1: Disconnect the throttle body electrical connector and vacuum lines.
Sub-step 2: Remove the throttle body from the intake manifold (typically involves 4-6 bolts; torque to manufacturer specifications).
Sub-step 3: Clean the throttle body using throttle body cleaner and a soft cloth, ensuring the butterfly valve operates smoothly.
Sub-step 4: Reinstall the throttle body and reconnect all electrical connectors and vacuum lines.

5. Final Checks

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the engine and allow it to reach operating temperature.
Sub-step 3: Perform a test drive to ensure the stalling issue has been resolved.
