Hey guys, So My VX Berlina was doing something very strange the other day. I was driving from Adelaide to Berri and as usual I had the cruise control on. All was fine on the way there but on the way back I was doing 110kph at 1500rpms and all of a sudden she jumped to 3000rpms. Gt home and havent driven it since until I know whats going on...
Is this a common thing and how can I fix it..

Any help would be appreciated.

Thanks in Advance..
