Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, safety goggles, gloves
Instructions:
1. Locate the fuel rail on the engine.
2. Connect the fuel pressure gauge to the Schrader valve.
3. Turn the ignition to the "On" position (do not start the engine) and check the pressure reading.
4. If pressure is below specifications, inspect the fuel pump and replace if necessary.
5. Check the fuel filter for clogs and replace if needed.

3. Ignition System Repair

Tools Required: Spark plug socket, torque wrench
Instructions:
1. Remove the ignition coils by unplugging the electrical connectors and unscrewing the bolts.
2. Remove the spark plugs using a spark plug socket, inspect for wear or deposits.
3. Replace any faulty spark plugs with OEM-spec replacements, ensuring proper gap setting.
4. Reinstall the ignition coils, securing them with bolts and reconnecting the wiring harness.

4. Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft cloth, screwdriver
Instructions:
1. Disconnect the air intake hose from the throttle body.
2. Spray throttle body cleaner onto a soft cloth and clean the throttle plate and surrounding area.
3. Reconnect the air intake hose securely.

5. Electrical System Check

Tools Required: Multimeter
Instructions:
1. Reconnect the negative battery terminal.
2. Use the multimeter to check the voltage at the battery with the engine running; it should read between 13.5 to 14.5 volts.
3. If the voltage is low, test the alternator and battery for faults and replace them as necessary.
