Hello, my name is***** will be helping you out! I have over thirteen years of experience in the automotive industry for numerous different makes & models. I enjoy doing what I do, it is my life.

It sounds like you have a fuel vapor issue commonly caused by the evap purge valve. If you have a scan tool we can verify this, if you do not then we can try replacing the valve and see if the problem continues which I doubt the problem will continue. Let me know if this helps :).
