Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the battery to prevent electrical issues during the repair.

2. Inspect and Change Engine Oil

• Sub-steps:
  1. Remove the oil drain plug using a socket set and drain the old engine oil into a pan.
  2. Replace the oil filter with a new one.
  3. Reinstall the drain plug and torque it to the manufacturer's specifications (usually around 25-30 ft-lbs).
  4. Fill the engine with new oil, using the recommended type and viscosity as per the owner’s manual.

3. Inspect and Replace Spark Plugs

• Sub-steps:
  1. Remove the ignition coils by unscrewing the bolts and disconnecting the electrical connectors.
  2. Use a socket wrench to remove the spark plugs.
  3. Inspect the condition of the spark plugs; replace with OEM parts if worn or fouled.
  4. Reinstall the new spark plugs and torque them to the specified value (usually around 13-15 ft-lbs).
  5. Reattach the ignition coils.

4. Check Fuel Injectors

• Sub-steps:
  1. Remove the engine cover if applicable to access the fuel rail.
  2. Disconnect the fuel lines and electrical connectors from the fuel injectors.
  3. Remove the fuel injectors from the rail and inspect for blockages.
  4. Clean or replace injectors as necessary.
  5. Reinstall everything and ensure all connections are secure.

5. Perform Compression Test

• Sub-steps:
  1. Remove the spark plugs to access the cylinders.
  2. Insert the compression tester into the spark plug holes.
  3. Crank the engine and record the compression readings.
  4. Compare the readings against the specifications in the service manual.
  5. Address any cylinders with low compression, which may involve further inspection or repairs.
