Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wires, depending on the engine configuration.
Use a spark plug socket to remove the spark plugs.
Inspect the spark plugs for signs of wear, fouling, or damage.
Replace with new spark plugs that meet OEM specifications.
Reinstall the ignition coils or spark plug wires.

3. Repair Exhaust Leaks

Locate the source of the popping noise by checking the exhaust system from the manifold to the tailpipe.
If a leak is found, tighten any loose connections or replace damaged components such as gaskets or pipes.
If the catalytic converter is damaged, remove it using an exhaust pipe cutter and replace it with a new unit.

4. Check and Adjust Fuel Mixture

If fuel delivery issues are suspected, check the fuel injectors for proper operation.
Clean or replace clogged injectors as necessary.
Adjust the fuel pressure regulator to ensure the correct fuel pressure is maintained.

5. Reassemble and Reconnect Battery

Ensure all components are securely reinstalled.
Reconnect the battery terminals.
Clear any error codes from the OBD-II scanner.
