I have a 96 ford taurus GL that is having power problems. When you give it gas it doesnt want to pick up speed. It hesitates and doesnt want to change gears.. I had the tranny and engine serviced about a week ago and it ran great until about a week later where it is having the same problems....any ideas?

 

First idea,,,take the car back to the shop.. if what ever they did seemed to help but then when back to the previous state after only a week id assume what ever they did wasnt done properly. just curious what all was done when you took it to the shop and you got it back and it seemed fine?
