Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect the Exhaust System

Tools Required: Socket set, flashlight
Sub-steps:
1. Raise the vehicle using jack stands for better access to the exhaust system.
2. Visually inspect the exhaust manifold for cracks or loose bolts.
3. Check the entire exhaust system for loose hangers or connections.
4. Tighten any loose bolts and replace any damaged components as necessary.

3. Check Spark Plugs and Ignition Coils

Tools Required: Spark plug socket, torque wrench
Sub-steps:
1. Remove the ignition coil from the suspected cylinder by unscrewing the retaining screws.
2. Carefully pull out the spark plug using the spark plug socket.
3. Inspect the spark plug for signs of wear, fouling, or damage. Replace if necessary.
4. Reinstall the spark plug and torque to the manufacturer’s specifications (typically around 13-15 lb-ft).
5. Reinstall the ignition coil and secure it with screws.

4. Reconnect Battery and Test

Reconnect the negative battery terminal securely.
Start the engine and listen for any popping noises or irregular sounds.
