Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, spark plug socket.
Remove the ignition coils by unscrewing them and disconnecting the electrical connectors.
Using a spark plug socket, remove the spark plugs from the cylinder head.
Inspect the spark plugs for wear and carbon buildup; replace if necessary.
Install new spark plugs, tightening to the manufacturer's specified torque (typically around 13-15 lb-ft).
Reattach the ignition coils, ensuring the connectors are secure.

3. Check and Replace Fuel Injectors (if necessary)

Tools Required: Fuel injector removal tool, torque wrench.
Relieve fuel pressure from the fuel system by removing the fuel pump relay and running the engine until it stalls.
Disconnect the fuel lines and electrical connectors from the fuel injectors.
Remove the fuel rail and inspect the injectors for clogs or leaks; replace if any issues are found.
Reinstall the fuel rail and reconnect the fuel lines and electrical connectors.

4. Repair or Replace Exhaust Components

Tools Required: Wrenches, socket set, exhaust hangers removal tool.
Inspect the exhaust system for any damaged sections, including the catalytic converter, muffler, and piping.
If any components are damaged, remove them by unbolting and replacing with new parts as necessary.
Ensure all bolts are torqued to the manufacturer's specifications.
