Most cars require a the throttle position sensor to be recalibrated when changed. If your car starts, which it should, drive it in “limp mode” to a good shop and they should have a scan tool to reset the sensor. Some cars have a relearn procedure you can do. Depends on the make and model. I would look for a video on you tube for the “relearn” process for your car before driving to the mechanic.
