Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, fuel pressure gauge, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool before starting work.

2. Address Fuel Delivery Issues

Check Fuel Pressure:
- Connect the fuel pressure gauge to the fuel rail.
- Turn the ignition to the "ON" position without starting the engine.
- Check the pressure reading against the manufacturer’s specifications (usually around 40-50 psi).
- If pressure is low, inspect the fuel pump and filter for blockages or failures.
Replace Fuel Filter (if necessary):
- Locate the fuel filter, usually along the fuel line.
- Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
- Disconnect fuel lines and remove the old filter.
- Install the new filter, ensuring proper orientation.

3. Inspect Ignition System

Check Spark Plugs:
- Remove spark plugs using a socket set.
- Inspect for wear or damage and replace if necessary.
- Gap the new spark plugs to the manufacturer’s specifications.
Inspect Ignition Coils:
- Check each ignition coil for proper operation using a multimeter.
- Replace any faulty ignition coils.

4. Clean Throttle Body

Remove Throttle Body:
- Disconnect the battery.
- Remove the intake duct to access the throttle body.
- Unplug electrical connectors and remove mounting bolts.
- Carefully detach the throttle body.
Clean Throttle Body:
- Use throttle body cleaner to remove carbon buildup.
- Ensure the throttle plate moves freely and is not sticking.
- Reinstall the throttle body and reconnect all components.
