Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.

2. Address Ignition System

Inspect and Replace Spark Plugs:
- Remove the ignition coil using a socket set.
- Unscrew and extract the spark plug using a spark plug socket.
- Install new spark plugs, tightening to the manufacturer's specifications (typically around 13-15 lb-ft).
Inspect and Replace Ignition Coils:
- If ignition coils are faulty, replace them by removing the screws holding them in place and disconnecting the electrical connector.
- Install new ignition coils and reconnect the electrical connectors.

3. Fuel System Inspection

Check Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "ON" position without starting the engine and check the pressure against specifications (typically 40-50 psi).
Inspect Fuel Injectors:
- Remove the fuel rail to access the injectors.
- Inspect for leaks or clogs, replacing any faulty injectors.

4. Air Intake System Check

Inspect Air Filter:
- Remove the air filter housing and check the air filter for dirt and blockages.
- Replace the air filter if it is dirty.
Check for Vacuum Leaks:
- Inspect hoses and connections for signs of wear or damage, repairing or replacing as necessary.

5. Exhaust System Evaluation

Inspect Catalytic Converter:
- Check for any signs of physical damage or excessive heat.
- If the catalytic converter is clogged, replacement may be necessary.
