Engine Revving on it's own
When I was sitting in traffic last night I noticed my engine appeared to be revving of it's own accord. Only up to 1,000 rpm every ten seconds or so.
Is that normal?

OK .. Golf.
Few things according to engine fitted will affect engine idle.
None are serious .. rather annoying. One or two can later cause engine stalling of it's own accord.
Idle control valve can get clogged and requires washing out.
Disconnect and reconnect the small pipe from the inlet manifold to the oil breather (before the butterfly) and see if idle stabilizes.
Brake servo pipe (from inlet manifold to servo) check for leakages (common on 1.6) That will effect idle.
Clean out carboned-up throttle body with carb cleaner. (open throttle wide and spray liberally/wipe out with paper)
You can do all of these pretty easily and cheaply. Need a can of carb cleaner!

Something a car DIY er could do ..
A garage would charge about an hour I suppose.
I did it various times while doing other servicing jobs on a car. You could wait for a service and ask that the throttle body and valve are cleaned out .. specifically.
You could also look at the servo pipe, I suppose!

Uh Oh, I'm seeing lots of words that mean nothing to me.
I did wonder about the fan so I kept checking the thermo and it just remained in the same place the whole time. It wasn't over heating.
I popped out a short while ago and noticed it doing it again while I was waiting at a junction. I could see in a reflection the headlights also seemed to dip a little bit when it was doing it.
