Solution

1. Preparation

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

2. Retrieve Diagnostic Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Record any error codes displayed and refer to a service manual for code definitions.

3. Inspect and Replace Spark Plugs

Remove the engine cover if necessary.
Use a socket wrench to remove the spark plug wire or coil over plug.
Carefully unscrew the old spark plugs using a spark plug socket.
Inspect for carbon fouling or excessive wear; replace if necessary with OEM specifications (typically NGK or Bosch).
Reinstall new spark plugs and reconnect wires or coils.

4. Check Fuel Injectors

Locate the fuel rail and remove any necessary covers.
Disconnect the fuel supply line (use a rag to catch any fuel).
Use a multimeter to test the resistance of each injector; replace any that are out of specification.
Clean or replace clogged injectors as necessary.

5. Inspect Air Intake System

Visually check the air filter for dirt or blockages and replace if necessary.
Inspect intake hoses for cracks or loose connections.
Clean the throttle body using an appropriate cleaner and a soft cloth.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any diagnostic trouble codes from the system.
