Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, wrench set, multimeter, timing light, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before opening the hood.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Remove the oil drain plug and drain the old oil into a pan.
3. Replace the oil filter with a new one.
4. Reinstall the drain plug and refill with the manufacturer-recommended oil.

3. Replace VVT Solenoids

Sub-steps:
1. Remove the engine cover to access the VVT solenoids.
2. Disconnect the electrical connectors from the solenoids.
3. Unbolt and remove the faulty VVT solenoids.
4. Install the new VVT solenoids and torque to manufacturer specifications (usually around 7-9 ft-lbs).
5. Reconnect the electrical connectors.

4. Inspect and Adjust Timing

Sub-steps:
1. Remove the timing cover to access the timing chain/belt.
2. Check for any wear or misalignment. Adjust the timing if necessary by aligning the timing marks.
3. If the timing chain/belt is worn, replace it according to the manufacturer's guidelines.
4. Reinstall the timing cover and ensure it is properly sealed.

5. Clear Codes

Sub-steps:
1. Use the OBD-II scanner to clear the error codes from the vehicle’s memory.
2. Reconnect the battery and start the engine to check for any reoccurring codes.
