Hello and welcome,My name is ***** ***** it will be my pleasure to assist you today.
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.I would suspect that the issue is either a faulty throttle or possibly and air leak in the intake system
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.
Please do not forge tto CLICK ON a positive rating
it is a general fault, does not point to a specific throttle
the fact the fault didnt return for 2 days points slightly more to the throttle than leak
