Solution

1. Preparation

Gather tools and parts required for service.
Disconnect the negative battery terminal to ensure safety while working on the vehicle.

2. Address Ignition System

Sub-steps:
- Remove the engine cover if applicable.
- Inspect and replace spark plugs if worn or fouled (Torque specification: 13 lb-ft).
- Test ignition coils using a multimeter; replace any faulty coils.

3. Fuel System Inspection

Sub-steps:
- Check fuel pressure using a fuel pressure gauge; ensure it meets manufacturer specifications.
- Clean or replace fuel injectors if they are clogged.
- Replace the fuel filter if it hasn’t been changed recently.

4. Air Intake System Check

Sub-steps:
- Remove and inspect the air filter; replace if dirty.
- Check and tighten any loose intake hoses or connections.
- Inspect the mass airflow sensor (MAF) for cleanliness; clean using MAF cleaner if necessary.

5. Exhaust System Examination

Sub-steps:
- Inspect the exhaust system for leaks, particularly around the manifold and catalytic converter.
- Use a backpressure gauge to test the catalytic converter; replace if excessive backpressure is detected.
