1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid electrical hazards.

2. Inspect and Replace Fuel System Components

Sub-steps:
1. Remove the fuel pump fuse and start the engine to relieve fuel pressure.
2. Check the fuel filter for clogs; replace if necessary.
3. Inspect the fuel pump operation using a fuel pressure gauge; replace if it does not meet specifications (usually around 30-50 psi).
4. Reconnect the fuel pump fuse.

3. Clean or Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the ignition coil connectors and remove the coils.
3. Inspect the spark plugs for wear; replace if the gap is out of specification or if they appear worn.
4. Clean the ignition coil terminals and reinstall or replace coils as needed.

4. Clean the Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
3. Ensure the throttle plate moves freely without obstruction.
4. Reattach the air intake duct securely.

5. Reconnect Battery and Test

Sub-steps:
1. Reconnect the battery terminals and ensure they are tight.
2. Start the engine and observe for any abnormal behavior.
3. Take the vehicle for a test drive to verify the stall issue has been resolved.
