Maintenance

Why did the shop that replaced the throttle body not do the reprogram? That should've been covered in the work. If you are not able to do this on your own, or if you are not comfortable doing so, have a shop (with a mechanic that is certified to do the work and accepted by the car manufacturer as certified to work on these cars) do the work, or have the dealership do the work. you may wish to shop around for a non-dealer mechanic shop first, they are often cheaper. Definitely at the very least call the dealer and ask. In the future, it's a good idea to find a shop you can trust that'll replace something, do all the necessary calibrations, and provide a warranty for such work. Please note: I am not a mechanic and do not have experience replacing throttle bodies on your car or any other car. I do however know what you are talking about (in the basic sense, I know what a throttle body is, and why it needs to be programmed after a replacement or similar).
