CAn you explain the surge a little better. ARe you talking about something to the effect that when you are just driving down the road (flat one) doing about 45-55 mph your engine will just rev up all by itself. If so my truck has done that pretty much the whole time I have had it. I have taken it to the dealer a couple of times when I first had it and they said nothing was wrong with it. I have just kept an eye on it. It doesn't always do it. It has not gotten any worse so I pretty much don't worry about it..
