Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical shorts.

2. Retrieve and Analyze Error Codes

Use an OBD-II scanner to read the error codes.
Document any codes related to misfires, fuel system issues, or sensor failures.

3. Inspect and Replace Spark Plugs

Remove the engine cover (if applicable).
Use a socket set to remove the spark plug wires or coils.
Inspect the spark plugs for wear; replace if necessary.
Use a torque wrench to install new spark plugs to the manufacturer's specifications (typically around 13 lb-ft).

4. Check and Replace Ignition Coils

If misfire codes are present, test each ignition coil with a multimeter.
Replace any faulty ignition coils with new ones.
Reassemble the ignition components once the tests are complete.

5. Inspect Fuel System

Check fuel pressure using a fuel pressure gauge.
Replace the fuel filter if clogged or dirty.
Ensure there are no leaks in the fuel lines.

6. Examine Air Intake and Vacuum System

Inspect the air filter for blockages; replace if dirty.
Check the intake manifold and hoses for cracks or disconnections.
Replace any damaged components to ensure proper air intake.
