Vauxhall Omega - Car is surging - passedit

Hi all new member and first post.

Have a Vauxhall Omega Elite 2.5 V6 auto 1999 petrol, the problem is that the engine surges when driving, not all the time on a journey but every time I use the car, up hills more so and the on flat and the car is not under load, thanks for your time, much appreciated!!

I have never seen engine surge on one of these.Are you sure it is not a gearbox problem?(presume its an auto).
