Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shorts.

2. Address Ignition Issues

• Inspect Spark Plugs:

  • Remove spark plugs using a spark plug socket.
  • Check for wear, carbon buildup, or damage.
  • Replace spark plugs if necessary (specifications: gap setting as per manufacturer).

• Test Ignition Coils:

  • Remove ignition coil connectors.
  • Use a multimeter to check the resistance values (specifications: refer to service manual).
  • Replace any faulty coils.

3. Fuel System Inspection

• Check Fuel Pressure:

  • Connect a fuel pressure gauge to the fuel rail.
  • Start the engine and observe the pressure readings (specifications: refer to service manual for acceptable range).
  • If pressure is low, inspect fuel pump and filter; replace if necessary.

• Inspect Fuel Filter:

  • Locate the fuel filter and check for clogs.
  • Replace the fuel filter if needed.

4. Transmission Fluid Check

• Inspect Transmission Fluid:
  • Locate the transmission dipstick and check fluid level.
  • If low, add the appropriate type of transmission fluid (refer to owner’s manual).
  • Inspect for signs of contamination or burnt smell; replace fluid if necessary.

5. Reassembly and Final Checks

• Reconnect all components and ensure all connections are secure.
• Reconnect the battery and clear any error codes using the OBD-II scanner.
• Start the engine and conduct a test drive to confirm the issue is resolved.
