The cruise control appears to be factory installed, but there are no lights indicators on the dashboard indicating when the cruise is on/off. Would the cruise control be an issue since it was not even turned on this morning, and I still had the issue. I have not even turned the cruise control on since Wednesday of last week when the issue first occurred. The car does have ABS. I will check the vacuum lines as well as clean the throttle body and see if that fixes the issue.
