Solution

1. Preparation

• Gather tools and parts needed for repair.
• Ensure the vehicle is parked on a flat surface and the engine is turned off.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Spark Plug

• Remove the ignition coil from cylinder one.
  • Tools Required: Socket set, ratchet.
• Remove the spark plug using a spark plug socket and ratchet.
• Inspect the spark plug for signs of wear, fouling, or damage.
• Replace the spark plug with a new one if necessary.
  • Torque the new spark plug to the manufacturer’s specification (typically 13-16 lb-ft).

3. Check Ignition Coil

• If damaged, replace the ignition coil with a new one.
  • Tools Required: Socket set.
• Reinstall the ignition coil securely.

4. Inspect Fuel Injector

• Remove the fuel injector connector for cylinder one.
• Test the injector using a multimeter to ensure proper resistance (typically 12-16 ohms).
• Replace the fuel injector if it is faulty or clogged.
  • Tools Required: Fuel line disconnect tool, socket set.
• Reinstall the connector and ensure it clicks into place.

5. Check for Vacuum Leaks
