Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, compression tester, oil filter wrench.
Safety Warnings: Disconnect the battery before working on electrical systems and allow the engine to cool before inspection.

2. Change Engine Oil

Sub-steps:
1. Raise the vehicle using jack stands and remove the undercarriage cover (if applicable).
2. Drain the old engine oil using an oil pan.
3. Replace the oil filter with a new one.
4. Fill the engine with manufacturer-recommended oil type and capacity (consult the owner's manual).
5. Start the engine and check for leaks.

3. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil or spark plug wires carefully.
2. Use a socket to remove the old spark plugs.
3. Check the gap on new spark plugs and install them according to specifications.
4. Reattach the ignition coils or spark plug wires securely.

4. Address Fuel Quality

Sub-steps:
1. Verify the fuel octane rating; switch to a higher octane fuel if necessary.
2. If using fuel additives, ensure they are suitable for the engine.

5. Perform Compression Test

Sub-steps:
1. Remove the spark plugs for better access.
2. Insert the compression tester into the spark plug hole for each cylinder.
3. Crank the engine and record the compression readings.
4. Compare the readings to manufacturer specifications; replace or repair any cylinders with low compression.
