Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, screwdrivers, jack and jack stands, safety goggles.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts during inspection.

2. Inspect Exhaust System

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect the exhaust pipes, muffler, and joints for any signs of damage or rust.
3. Tap on the exhaust components with a rubber mallet to check for loose parts.
4. Repair or replace any damaged sections of the exhaust system.

3. Check Ignition System

Sub-steps:
1. Remove the spark plug wires and inspect the spark plugs for wear (look for carbon buildup or damage).
2. Replace any faulty spark plugs with the manufacturer's recommended type.
3. Inspect ignition coils for proper function and replace if necessary.

4. Examine Fuel System

Sub-steps:
1. Check the fuel pressure using a fuel pressure gauge to ensure it meets manufacturer specifications.
2. Inspect fuel injectors for clogs; clean or replace them if necessary.
3. Replace the fuel filter if it is clogged or has not been changed in a while.

5. Test Drive and Monitor

After making the repairs, reconnect the battery and start the engine.
Take the vehicle for a test drive to ensure the popping noise has been resolved.
