Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and securely supported if needed.

2. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the ignition coils by unbolting and disconnecting the electrical connectors.
2. Extract the spark plugs using a spark plug socket and ratchet.
3. Inspect the spark plugs for signs of wear, fouling, or damage; replace if necessary.
4. Gap new spark plugs according to manufacturer's specifications and install them.
5. Reattach the ignition coils securely.

3. Check and Repair Exhaust Leaks

Sub-steps:
1. Inspect the exhaust manifold and connections for cracks or loose bolts.
2. Use a high-temperature exhaust sealant to seal minor leaks or replace gaskets as needed.
3. Retighten all connections to the manufacturer’s torque specifications.
4. Start the engine and listen for any remaining exhaust leaks.

4. Inspect Fuel System

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "on" position without starting the engine and check pressure readings.
3. If pressure is low, check the fuel filter for clogs and replace if necessary.
4. Inspect the fuel pump operation and replace if malfunctioning.
