I am having a weird occurance with my cruise control. When I set the cruise going about 60 or so, all is fine. When I set the cruise at 75-85, it feels like I someone pressing on and off the gas non stop. It is very noticable. I am no mechanic by any stretch, but it feels almost like the boost from the turbo keeps kicking in and out. Does anyone know anything about this. When I am driving at these speeds without cruise, it doesn't do that at all. I will end up getting someone to look at it, but I would like to know what the problem is/could be before I take it in, so I don't get hosed for the lack of car knowledge. Thanks in advance.
