Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cool.
Disconnect the battery's negative terminal for safety.

2. Access Ignition Components

Remove the engine cover if applicable (using a socket set).
Disconnect the ignition coils from the wiring harness.
Remove the ignition coils (typically requires a socket or wrench).

3. Inspect and Replace Spark Plugs

Remove spark plugs using a spark plug socket.
Inspect the spark plug condition; replace if worn or fouled.
Install new spark plugs with a torque specification of 13 lb-ft (or as specified by the manufacturer).

4. Check Fuel Injectors

Use a fuel pressure gauge to check the fuel pressure (should match manufacturer specifications).
If pressure is low, check the fuel pump and filter for issues.
If injectors are faulty, replace them with new units.

5. Reassemble and Test

Reinstall ignition coils and reconnect the wiring harness.
Reconnect the battery's negative terminal.
Start the engine and monitor for any abnormal sounds or lights.
