Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, jack and jack stands, safety goggles.
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery to avoid electrical issues.

2. Inspect Exhaust System

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Visually inspect the exhaust system for cracks, loose pipes, or damaged hangers.
3. If damage is found, replace the affected sections or tighten loose connections as necessary.

3. Check and Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil covers using a socket set.
2. Disconnect the ignition coils and remove them to access the spark plugs.
3. Inspect the spark plugs for wear, carbon fouling, or damage.
4. Replace spark plugs if necessary, ensuring they are gapped to manufacturer specifications.
5. Reinstall ignition coils and covers.

4. Inspect and Repair Intake System

Sub-steps:
1. Visually inspect the intake manifold and hoses for cracks or loose connections.
2. Tighten any loose clamps or fittings to ensure a proper seal.
3. Replace any damaged hoses or components as necessary.

5. Test Fuel Pressure

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail service port.
2. Turn the ignition to the "ON" position without starting the engine and observe the pressure reading.
3. Compare the reading to the manufacturer’s specifications. If it's low, check the fuel pump and filter for issues.
