Hello Tim and Welcome! I'm Billy and i will assist you with your inquiry. Feel free to ask if any further info is needed.
My apologies for the delay, thank you for your patience.
when you say dogs out, you mean it hesitates, it has poor performance?
Can you please specify what exactly happens? and if you turn off in the middle of a hill, and then restart, does it do this again?
what mileage do you have on this?
do you have any warning lights on dash?
