Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Spark Plugs

Remove the engine cover (if applicable) using a socket set.
Disconnect the ignition coils and remove them to access the spark plugs.
Inspect spark plugs for wear or damage; replace if necessary.
Reinstall the ignition coils and engine cover, ensuring all connections are secure.

3. Repair or Replace Exhaust Components

If exhaust leaks are found, remove the damaged section using an exhaust pipe cutter or saw.
Install a new exhaust gasket or sealing compound where necessary and replace the damaged section with new exhaust pipe or components.
Tighten all clamps and bolts to manufacturer specifications.

4. Address Fuel System Issues

If fuel pressure is low, replace the fuel filter and inspect the fuel pump functionality.
Clean or replace fuel injectors if clogged or malfunctioning.

5. Test and Reconnect Battery

Reconnect the battery.
Start the engine and listen for any remaining popping sounds.
