Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Repair Exhaust System

Visual Inspection:
- Check all exhaust connections and joints for signs of leaks.
- Look for rust, holes, or any physical damage on the exhaust pipes and muffler.
Repair or Replace Components:
- If leaks are found, replace the affected gaskets or use exhaust sealant as needed.
- For damaged pipes or mufflers, remove the affected section using a socket set, and replace it with a new component, ensuring proper alignment.

3. Diagnose and Adjust Air-Fuel Mixture

Check Air-Fuel Ratio:
- Use a wideband O2 sensor to monitor the air-fuel mixture during operation.
- If readings are outside the normal range, adjust the fuel delivery system (e.g., fuel injectors) or modify the engine management software if the vehicle is tuned.
Test Drive:
- After adjustments, take the vehicle for a test drive to ensure the popping noise is resolved.

4. Inspect and Replace Ignition Components

Check Spark Plugs and Coils:
- Remove spark plugs using a spark plug socket and inspect for wear or fouling.
- Replace spark plugs if necessary and check ignition coils for proper operation.
Reinstall Components:
- Reinstall spark plugs with the manufacturer’s specified torque settings and reconnect ignition coils.
