Could it be my auxiliary air valve? Or have you got any other suggestions? :/

That is strange. What happens if you put the brakes on with the car at a standstill? I know when I had an earth fault with the indicators the revs would drop by 100rpm at the traffic lights everytime they came on. With all consumers on the revs drop a bit again. I wonder if you have a vacuum leak from the servo.
How much fuel do you have in the tank? When running low (which is now never in my car!) my car would sometimes cut out or try to cut out dependant on the amount of fuel in the tank.
The AAV shouldn't really affect it. It is quite simply a disc which is open (thus allowing extra air into the engine at low RPM via bypassing the throttle) which will eventually close up once the element heats up off its 12V supply.
