I've just done the PCV changeout, put it all back together, fired up, and let it idle. Sounded okay, but when the car is sitting still and I rev the engine to say 2000 rpm it hunts, very slightly, not really enough to show on the revcounter, appears as a twitch more than anything, but enough to be audible. Seems to be steady enough at idle.

Any ideas?

Air leaks did occur to me, and I checked the idle control valve connections. I'll go back outside and try spraying selected bits with WD40 and see what happens.
