Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge, compression tester.
Safety Warnings: Disconnect the battery before working on electrical components. Allow the engine to cool before working on it.

2. Address Ignition System

Sub-steps:
1. Remove engine cover (if applicable) to access ignition components.
2. Inspect spark plugs for wear; replace if electrodes are worn or fouled.
3. Check ignition coils for proper function using a multimeter; replace any faulty coils.
4. Reinstall components and cover.

3. Inspect Fuel System

Sub-steps:
1. Locate the fuel rail and check for leaks or damage.
2. Use a fuel pressure gauge to measure the fuel pressure; compare with manufacturer specifications.
3. Remove and clean or replace clogged fuel injectors.
4. Ensure the fuel pump is functioning correctly.

4. Examine Air Intake System

Sub-steps:
1. Remove the air filter and inspect it; replace if dirty or clogged.
2. Check intake hoses for cracks or disconnections; replace if necessary.
3. Clean the throttle body if it appears dirty.

5. Test Engine Compression

Sub-steps:
1. Remove spark plugs to allow for compression testing.
2. Insert the compression tester into each cylinder and crank the engine.
3. Record the compression readings and compare them to specifications; investigate low readings.
