Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid electrical shorts during repairs.

2. Inspect and Replace Ignition Components

Inspect Spark Plugs:
- Remove the ignition coils using a socket set.
- Extract the spark plugs and inspect for wear or fouling.
- Replace with OEM or recommended spark plugs if necessary.
Replace Ignition Coils (if faulty):
- Remove the faulty ignition coil(s).
- Install new ignition coil(s) and ensure they are seated properly.
- Reconnect the electrical connectors.

3. Examine and Repair Fuel System

Check Fuel Pressure:
- Attach a fuel pressure gauge to the fuel rail.
- Start the engine and monitor pressure; compare to specifications.
Inspect Fuel Injectors:
- Remove fuel injectors and clean or replace if clogged.
- Reinstall injectors ensuring proper sealing.

4. Air Intake and Exhaust Inspection

Check Air Intake:
- Inspect air filter and replace if dirty.
- Check intake hoses for cracks or leaks and replace as necessary.
Examine Exhaust System:
- Inspect for any visible damage or blockages.
- Replace damaged components or repair exhaust leaks.

5. Engine Compression Test

Perform a compression test on each cylinder using a compression gauge.
If compression is low, further diagnostics may be needed to assess potential internal engine damage.
