Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, throttle body cleaner, cleaning rags.
Disconnect the battery to ensure safety while working on electrical components.

2. Fuel System Inspection

Sub-steps:
1. Remove the fuel pump relay and use a fuel pressure gauge to check the fuel pressure; it should be within manufacturer specifications (typically 30-45 PSI).
2. If low pressure is detected, check the fuel filter for clogs and replace if necessary.
3. If the fuel filter is clear, inspect the fuel pump for proper operation and replace if faulty.

3. Air Intake System Cleaning

Sub-steps:
1. Remove the air intake hose connected to the throttle body.
2. Inspect the air filter; replace if dirty or clogged.
3. Using throttle body cleaner, clean the throttle body and any carbon deposits in the intake manifold.
4. Reattach the air intake hose ensuring all clamps are secure.

4. Ignition System Check

Sub-steps:
1. Remove the spark plugs using a socket and inspect for wear or fouling; replace if necessary.
2. Test the ignition coils with a multimeter to ensure they are within specifications; replace any that are out of range.
3. Reinstall new or cleaned spark plugs and reconnect ignition coils.

5. Electrical System Assessment

Sub-steps:
1. Use a multimeter to check the battery voltage; it should be between 12.4V and 12.7V when fully charged.
2. Inspect the alternator output while the engine is running; it should be between 13.7V and 14.7V.
3. If either the battery or alternator fails the test, replace as necessary.
