Mine sits at 1100 then drops to 900. Perfectly normal.

Yes and after coming to a junction. Apparently its normal for the revs to be held higher for a short time before dropping.

Its not dropping momentarily when the radiator fan kicks in is it? If so that would be perfectly normal.

Doubt it, cleaning the ISCV dont do shit IMO, but if you got carb cleaner you might aswell.

Check your air filter for cleanliness and clean out the throttle body too.
