Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, mechanic's stethoscope, compression tester.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Address Exhaust System Issues

Inspect and Repair:
1. Raise the vehicle using jack stands and secure it.
2. Inspect the entire length of the exhaust system for cracks or loose connections.
3. Tighten any loose clamps or bolts.
4. If a crack is found, replace the damaged section of the exhaust pipe or muffler.
5. Use exhaust sealant for minor leaks and reseal joints as necessary.

3. Replace Ignition Components

Replace Spark Plugs and Coils:
1. Disconnect the negative battery terminal.
2. Remove the ignition coils by unbolting them and disconnecting the electrical connectors.
3. Remove the old spark plugs using a spark plug socket.
4. Install new spark plugs, ensuring they are gapped correctly as per specifications.
5. Reinstall the ignition coils and reconnect electrical connectors.

4. Repair Intake System

Check and Seal Vacuum Leaks:
1. Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
2. Replace any damaged hoses.
3. Ensure the intake manifold is securely fastened to the engine.

5. Test Engine Compression

Perform Compression Test:
1. Remove the spark plugs to access the cylinder heads.
2. Insert the compression tester into the spark plug hole of each cylinder.
3. Crank the engine and record the compression readings.
4. Compare readings to manufacturer specifications; low readings indicate internal engine problems.
