    Do you have any Service Engine Soon Lights or Service Vehicle Soon Lights on? If so, theses lights will mean that a computer code has been stored and this code can help you determine what the problem is. It sounds like your vehicle is in some kind of a 'limp home mode ' that is preventing it from going normal speeds.
