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 prevent electrical shorts.

2. Inspect and Replace Spark Plugs

Remove the ignition coils by unscrewing the bolts and disconnecting the wiring harness.
Use a spark plug socket to remove the spark plugs.
Inspect the spark plugs for wear; replace any that are damaged or fouled.
Install new spark plugs to manufacturer's specifications (typically torque to 13 lb-ft).
Reinstall the ignition coils ensuring they are seated properly.

3. Check and Replace Ignition Coils (if necessary)

If the ignition coils were found faulty, remove them after spark plug replacement.
Disconnect the wiring harness and unscrew any mounting bolts.
Install new ignition coils, ensuring they are compatible with the vehicle model.
Reconnect the wiring harness and secure the coils in place.

4. Fuel Injector Inspection and Cleaning

Remove the fuel rail by unscrewing it from the intake manifold, ensuring to relieve fuel pressure beforehand.
Inspect the fuel injectors for clogs or leaks; clean them using a fuel injector cleaning kit.
Reinstall the fuel rail and ensure all connections are secure.

5. MAF Sensor Cleaning (if necessary)

Disconnect the MAF sensor’s electrical connector.
Remove the MAF sensor from the air intake duct (usually held by screws or clips).
Clean the MAF sensor with a specialized MAF cleaner; allow it to dry completely before reinstalling.
