Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, compression tester, engine oil, fuel injector cleaner.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative terminal of the battery.

2. Change Engine Oil

Sub-steps:
1. Remove the oil drain plug with a socket set and drain the old oil into a suitable container.
2. Replace the oil filter using an oil filter wrench; apply a small amount of new oil on the rubber gasket of the new filter before installation.
3. Reinstall the drain plug and tighten to manufacturer specifications (typically around 30 ft-lbs).
4. Fill the engine with the recommended grade of oil (check owner's manual for specifications).
5. Start the engine and let it idle for a few minutes, then check for leaks.

3. Clean Fuel Injectors

Sub-steps:
1. Add a quality fuel injector cleaner to the fuel tank as per manufacturer instructions.
2. Run the vehicle until the cleaner is consumed, ideally during a highway drive to ensure thorough cleaning.
3. Monitor the engine for any changes in the knocking noise.

4. Address Internal Engine Issues

Sub-steps:
1. If the compression test shows low numbers, it may indicate worn piston rings or valves. Consult a professional for potential rebuild or replacement.
2. Inspect and replace the timing belt/chain if it appears worn or out of alignment.
3. If mechanical issues are confirmed, consider further disassembly of the engine for repair or replacement of damaged components.
