Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety during the repair.
Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge.

2. Inspect and Replace Spark Plugs

Remove the ignition coils by unscrewing the mounting bolts and gently pulling them out.
Remove the old spark plugs using a spark plug socket.
Inspect the spark plugs for signs of fouling or wear.
Install new spark plugs, ensuring they are gapped correctly according to manufacturer specifications.
Reinstall the ignition coils and torque to the specified value.

3. Repair Exhaust System

If leaks are found in the exhaust system, identify the damaged section.
Remove any damaged exhaust components (e.g., muffler, pipe) using a socket set.
Install a new exhaust component, ensuring all gaskets and seals are in place.
Torque all connections to manufacturer specifications and check for leaks after installation.

4. Check and Secure Intake System

Inspect all intake hoses and connections for cracks or looseness.
Replace any damaged hoses and re-secure all connections.
Ensure the air filter is clean and properly seated.

5. Test Fuel System

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "on" position (do not start the engine) and check the fuel pressure reading against manufacturer specifications.
If pressure is low, check the fuel pump and filter for issues; replace as necessary.
