Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent accidental electrical shorts.

2. Check and Replace Spark Plugs

Sub-steps:
- Remove the ignition coil cover if necessary.
- Unscrew and remove old spark plugs using a spark plug socket.
- Inspect the spark plugs for carbon buildup or damage.
- Install new spark plugs to manufacturer specifications (typically torque to 13-16 lb-ft).
- Reconnect ignition coils.

3. Inspect and Replace Fuel Injectors

Sub-steps:
- Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
- Disconnect fuel lines and electrical connectors from the injectors.
- Remove old fuel injectors and replace with new ones.
- Reconnect fuel lines and electrical connectors ensuring they are secure.

4. Check for Vacuum Leaks

Sub-steps:
- Inspect all vacuum hoses and gaskets for cracks or disconnections.
- Use a smoke machine or carb cleaner to identify leaks.
- Replace any damaged hoses and reseal gaskets as needed.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and check if the engine light remains off.
