To keep this short and sweet... I was travelling down the motorway a couple of weeks ago, doing about 75mph. Tried to put my foot down to overtake, and there was no acceleration. Very slowly the speed dropped until i was at 60. Dropped into 4th gear, still nothing. By the time i got to a services i was at 55mph. Got out, had a brew, started her up again, no problems. Anybody have any suggestions what might of happened? Its 06 plate, had enough fuel/oil/water etc. Since this incident no further problems, as yet. Need suggestions before i go to a garage and they say its something crazy that will cost a fortune to fix.
