Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is cool.
Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, cleaning supplies for throttle body.
Safety Warnings: Disconnect the battery before working on electrical components.

2. Address Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve any stored fault codes and note their descriptions.
If codes related to the ignition or fuel system are present, address those components first.

3. Replace Spark Plugs

Remove the engine cover if necessary.
Disconnect the ignition coil connectors and remove the ignition coils.
Use a spark plug socket to remove the spark plugs.
Inspect the old plugs; replace them with new ones if they are worn or fouled.
Torque the new spark plugs to the manufacturer's specifications.

4. Check and Adjust Fuel Pressure

Connect the fuel pressure gauge to the fuel rail.
Start the engine and observe the pressure reading. Compare it to the manufacturer's specified pressure.
If pressure is low, inspect the fuel pump and filter for issues, replacing as necessary.

5. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use a throttle body cleaner and a soft cloth to clean the throttle body, removing any carbon buildup.
Reconnect the air intake duct securely.

6. Reassemble and Test

Reinstall the ignition coils and connectors.
Reconnect the battery and start the engine.
Allow the engine to idle and perform a test drive to check for resolution of the stuttering issue.
