Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, timing light, multimeter, torque wrench.
Disconnect the negative battery terminal to avoid electrical short circuits during the repair.

2. Inspect and Replace Spark Plugs

Remove the engine cover if necessary.
Disconnect the ignition coils from the spark plugs.
Use a socket to remove old spark plugs, noting their order for reinstallation.
Inspect new spark plugs for correct gap size and install them to the manufacturer's specifications (typically 13-15 ft-lbs torque).
Reconnect the ignition coils and engine cover.

3. Check and Adjust Ignition Timing

Connect the timing light to the battery and ignition coil.
Start the engine and allow it to reach normal operating temperature.
Point the timing light at the timing marks on the crankshaft pulley.
Adjust the ignition timing if it is out of specification according to the service manual.

4. Replace Knock Sensor (if faulty)

Locate the knock sensor, typically found on the engine block.
Disconnect the electrical connector from the knock sensor.
Remove the sensor using a socket.
Install the new knock sensor, ensuring it is tightened to the specified torque (usually around 15-20 ft-lbs).
Reconnect the electrical connector.
