Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Scan and Identify Codes

Using the OBD-II scanner, retrieve the error codes.
Note any specific codes related to misfires, fuel system, or ignition issues.

3. Inspect and Replace Ignition Components

Tools Required: Socket set, torque wrench
Remove the engine cover if necessary.
Unscrew and remove the spark plugs using the socket set.
Inspect the spark plugs for wear and replace them if necessary (OEM recommended specifications).
Check the ignition coils for damage and replace any faulty coils.

4. Fuel System Inspection

Tools Required: Fuel pressure gauge
Connect the fuel pressure gauge to the fuel rail.
Start the engine and monitor the fuel pressure; compare with manufacturer specifications.
If pressure is low, check for clogs in the fuel filter or a failing fuel pump, replacing components as needed.

5. Air Intake and Vacuum Inspection

Remove the air intake duct and inspect for blockages or damage.
Check the intake manifold for vacuum leaks using a smoke tester if available.
Replace any damaged hoses or components.

6. Reassemble and Test

Reinstall any removed components in reverse order of removal.
Reconnect the battery.
