Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Repair Exhaust System

Tools Required: Socket set, jack stands, exhaust hanger removal tool, safety gloves.
Visually inspect the exhaust pipes, muffler, and catalytic converter for holes or corrosion.
If leaks are found, use exhaust repair tape for minor holes, or replace the damaged section of the exhaust pipe or muffler as necessary.
Ensure all clamps are tight and exhaust hangers are in good condition.

3. Address Engine and Drivetrain Issues

Tools Required: OBD-II scanner, torque wrench, multimeter (if necessary).
If error codes are present, research and address the specific issues indicated (e.g., replace faulty sensors).
Inspect engine mounts: if damaged, replace them to reduce engine movement.
Check CV joints and axles: replace any worn or damaged components to eliminate noise and restore proper function.

4. Reassemble and Test

Reconnect the battery.
Start the engine and let it idle, listening for any remaining sounds.
Conduct a test drive to ensure the popping sound has been eliminated during acceleration.
