Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, compression tester, fuel pressure gauge.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Change Engine Oil

Sub-steps:
1. Remove the oil drain plug using a wrench and drain the old oil into a suitable container.
2. Replace the oil filter using an oil filter wrench; lubricate the rubber gasket of the new filter with fresh oil before installation.
3. Reinstall the oil drain plug and torque it to the manufacturer’s specifications (typically 20-30 ft-lbs).
4. Fill the engine with manufacturer-recommended oil type (typically 0W-20 for Honda).
5. Start the engine and let it idle for a few minutes; check for leaks.

3. Replace Spark Plugs

Sub-steps:
1. Remove the ignition coils by unscrewing the retaining bolts; disconnect the electrical connectors.
2. Use a spark plug socket to remove the old spark plugs.
3. Inspect the spark plugs for wear or deposits; replace with OEM or equivalent spark plugs.
4. Gap the new spark plugs according to manufacturer specifications (typically 0.044 inches).
5. Install the new spark plugs and torque them to the specified value (typically 13-16 ft-lbs).
6. Reinstall the ignition coils and reconnect the electrical connectors.

4. Fuel System Inspection

Sub-steps:
1. Check fuel quality; drain contaminated fuel if necessary.
2. Replace the fuel filter if applicable; consult the vehicle service manual for specific procedures.
3. Use a fuel injector cleaner additive in the fuel tank to clean injectors.
4. Inspect fuel injectors for proper operation; replace if faulty.

5. Engine Timing Check

Sub-steps:
1. Remove any necessary covers to access the timing belt/chain.
2. Check alignment of timing marks according to service manual.
3. If timing is off, realign or replace the timing belt/chain as necessary.
