Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery for safety if working on electrical components.

2. Address Ignition System

Remove Engine Cover:
- Use a socket set to remove screws securing the engine cover.
- Carefully lift the cover off and set it aside.
Inspect and Replace Spark Plugs:
- Use a spark plug socket to remove each spark plug.
- Inspect for wear (burn marks, cracks) and replace if necessary with OEM spark plugs, torquing to manufacturer's specifications (typically 18 lb-ft).
Check and Replace Ignition Coils:
- Disconnect the electrical connector from each ignition coil.
- Remove the bolts holding the coils in place.
- Replace faulty coils with new OEM coils and ensure they are securely fastened.

3. Fuel System Inspection

Check Fuel Injectors:
- Remove the fuel rail, ensuring to relieve fuel pressure first.
- Inspect injectors for clogs or leaks; clean or replace as necessary.
- Reinstall fuel rail, ensuring proper torque specifications (typically 18 lb-ft).
Perform Fuel Pressure Test:
- Connect a fuel pressure gauge to the fuel rail.
- Start the engine and verify that pressure meets manufacturer specifications (usually around 50-60 psi).

4. Air and Exhaust System

Inspect Air Filter:
- Remove the air intake duct.
- Check the air filter for dirt or blockages; replace if necessary.
Examine Exhaust System:
