Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, multimeter, fuel pressure gauge, cleaning supplies.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect and Repair Fuel System

Check Fuel Pump Operation
- Reconnect the battery.
- Turn the ignition to the "ON" position without starting the engine to prime the fuel system.
- Listen for the fuel pump operation; if not audible, the pump may need replacing.
Replace Fuel Filter (if necessary)
- Locate the fuel filter (usually near the fuel tank).
- Use a socket set to disconnect the fuel lines and remove the filter.
- Install a new fuel filter, ensuring proper orientation and secure connections.

3. Inspect and Repair Ignition System

Check Spark Plugs and Coils
- Remove the ignition coil covers using a socket set.
- Inspect spark plugs for wear or damage; replace if necessary.
- Test ignition coils with a multimeter to ensure they are within the specified resistance range and replace as needed.

4. Clean Throttle Body

Throttle Body Cleaning
- Disconnect the throttle body connector and remove the throttle body from the intake manifold.
- Use throttle body cleaner to remove carbon buildup on the throttle plate and inside the body.
- Reinstall the throttle body and reconnect the connector.

5. Test and Verify Repairs

Reconnect the battery and start the engine.
Allow the engine to idle and check for any abnormal noises or signs of stalling.
Test drive the vehicle to ensure it accelerates smoothly without stalling.
