Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, compression tester, stethoscope, oil filter wrench.
Safety Warnings: Ensure the engine is cool before starting; disconnect the battery to avoid electrical shorts.

2. Change Engine Oil

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Place an oil drain pan under the oil pan and remove the drain plug to drain the oil completely.
3. Replace the oil filter using an oil filter wrench.
4. Install a new drain plug, tightening to the manufacturer’s torque specification.
5. Refill the engine with the recommended oil type and quantity.

3. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coils or spark plug wires to access the spark plugs.
2. Use a spark plug socket to carefully remove each spark plug.
3. Inspect and replace with new spark plugs of the specified type and gap.
4. Reinstall the ignition coils or spark plug wires securely.

4. Address Compression Issues

Sub-steps:
1. Use a compression tester to measure the pressure in each cylinder.
2. If readings are low, perform a leak-down test to identify specific issues.
3. Depending on findings, consider repairs such as replacing piston rings or cylinder head gasket.

5. Inspect and Replace Engine Mounts (if necessary)

Sub-steps:
