Ever driven a car that's running out of fuel? Dying and picking up?
That's surging.

omg, thats what my EA has been doing!! I've been trying to explain it for ages but wasn't sure how. sometimes it will keep cutting out for seconds really quickly making thre car jerk and the tacho moves up and down really quickly!! how do I fix it, i've changed the fuel filter but that didn't fix it. I'm gonna try and test the fuel pressure when I buy a guage, would this be worth it?

Have a look at your airflow sensor.It may have dirt on the hot wires.You can remove it from the housing for accurate cleaning.Its another place to look.

seen as though the problem arose just after the automatic was done, could it perhaps be the neutral drive switch have something to do with this? (not sure if the AU's have these)
