My wife has a 1.4 16V Corsa with 80k on the clock. It has generally been faultless since we've had it. However, it has recently gained a few (related) problems.
When driving on steady throttle, it will randomly stutter 4-5 times or until you lift off.
Sometimes when driving in a "spirited" manner (as the wife does, sometimes) or when wanting to quickly reverse into our driveway, it will stall as soon as you put your foot on the clutch. For example, if you quickly pull up at the side of the road in 3rd, put your foot on the clutch to quickly select reverse to go back into the drive, it will die totally as if you've switched the engine off (ignition is still on)
Sometimes in traffic with her foot on the clutch or when in neutral, she's felt it idle a little roughly, though I've never felt it as I seldom drive it.
Dirty throttle body? Clogged fuel filter? Something else?
Its never been on a motorway in its 9 year life and has had nothing but lady owners who trundle round town in it - so I'm tempted to stick a bottle of Redex in it.

Sounds very much like a sticky Idle Control Valve.

Is the idle control valve cleanable or does it need to be replaced?

You can clean them. But, it's an arse of a job to get to. May aswell change it for a new one while your there.

Its location and removal is covered in a Haynes manual, I presume?

Yes, i presume so. It's located on the side of the throttle body. The throttle body is down the right hand side of the engine. You'll need to take the top half of the inlet off.

I've had the inlet manifold top half off before when I changed the rocker cover gasket - so I should be OK doing it again.
I'm guessing the throttle body is just below the large diameter rubber tube that you have to disconnect to remove the inlet manifold.

It once came on for about 20 seconds but then went out on its own.
