I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.


thank you for your attention to the rating requirement.


this is most likely due to a failed airflow sensor or air leak / restriction.


I would suggest replacing the airflow sensor.


Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
