Was driving earlier and something happened the car. Seems as though a drive belt is slipped or something when I get into the highways revs. You can hear it In the engine bay. Happened In 2nd gear. Seems slightly hesitant when In nuetral and accelerated. The exhaust is blown but I dont think they are associated. It is driving ok apart from that. Any idea? Feels like the car is almost wheel spinning but coming from under the bonnet?
