Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure safety gear is worn (gloves, goggles).
• Disconnect the battery to avoid electrical shock.

2. Address Ignition Issues

1. Remove Engine Cover (if applicable)
   • Use a socket set to remove bolts securing the cover.
2. Inspect Spark Plugs
   • Remove spark plugs using a spark plug socket.
   • Check for fouling or wear; replace if necessary.
3. Check Ignition Coils
   • Unplug each ignition coil and inspect for cracks or damage.
   • Test using a multimeter for proper resistance; replace faulty coils.

3. Fuel System Inspection

1. Check Fuel Pressure
   • Connect a fuel pressure gauge to the fuel rail.
   • Start the engine and check if the pressure is within specifications; replace fuel pump if low.
2. Inspect Fuel Injectors
   • Remove injectors for cleaning or replacement if found faulty.
   • Use a fuel injector cleaner to ensure proper operation.

4. Check Air Intake System

1. Inspect Air Filter
   • Remove the air filter and inspect for dirt or blockages; replace if necessary.
2. Examine Intake Hoses
   • Check hoses for cracks or disconnections; replace worn hoses.

5. Exhaust System Check

1. Inspect Exhaust for Blockages
   • Check for any visible damage or restrictions in the exhaust system.
   • Replace any damaged sections of exhaust piping.

6. Final Checks

• Reconnect the battery.
• Start the engine and monitor for any abnormal noises or symptoms.
