Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shock.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrenches
Check fuel pressure:
1. Locate the fuel rail on the engine.
2. Connect the fuel pressure gauge to the test port on the fuel rail.
3. Turn the ignition to the "ON" position (do not start the engine) and check the fuel pressure reading against manufacturer specifications.
4. If the pressure is low, inspect the fuel pump and fuel filter for issues.

3. Ignition System Repair

Tools Required: Socket set, torque wrench
Replace spark plugs:
1. Remove the ignition coil cover if applicable.
2. Unplug the ignition coils and remove them.
3. Use a spark plug socket to remove old spark plugs.
4. Install new spark plugs, ensuring they are properly gapped according to specifications.
5. Reattach the ignition coils and cover.

4. Throttle Body Cleaning

Tools Required: Throttle body cleaner, rag, screwdriver
Clean the throttle body:
1. Disconnect the air intake duct from the throttle body.
2. Spray throttle body cleaner onto a rag and wipe the inside of the throttle body to remove carbon deposits.
3. Reassemble the air intake duct securely.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes.
Test drive the vehicle to ensure the stalling issue is resolved.
