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 to ensure safety while working on electrical components.

2. Retrieve and Address Error Codes

Tools Required: OBD-II scanner
Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition (do not start the engine) and read the error codes.
Note the codes and look them up to determine the underlying issue.

3. Inspect and Replace Spark Plugs and Ignition Coils

Tools Required: Socket set, torque wrench, dielectric grease
Remove the engine cover if applicable.
Disconnect the electrical connectors from the ignition coils.
Unscrew and remove the ignition coils and spark plugs.
Inspect the spark plugs for wear and replace them if necessary.
Replace any faulty ignition coils.
Reinstall the spark plugs and torque them to the manufacturer's specifications.

4. Check Fuel System Pressure

Tools Required: Fuel pressure gauge
Locate the fuel pressure test port on the fuel rail.
Connect the fuel pressure gauge and turn on the ignition to prime the fuel system.
Read the pressure on the gauge and compare it to the manufacturer's specifications.
If pressure is low, consider replacing the fuel filter or fuel pump.

5. Verify and Reassemble

Reconnect all components and battery terminals.
Clear the error codes using the OBD-II scanner.
Start the engine and check for any warning lights.
