Idle Issue when cold!

[Adams-Sideways]

Hi guys, having a little issue with idle at the moment. When i start the car sometimes the idle dives up and down very uniformly from really low nearly stalling back up to 1600rpm? about 10 times (once a second very uniform)

Does the same thing at traffic lights or junctions, all in the first 2-3 minutes of driving. As soon as the car warms up its fine?

What can i test/replace?

Any ideas?

Thanks

Clean out the ICV, this was the same problem another zoner had a few days ago.

1. Disconnect the ICV from the manifold \ Big Rubber Boot
2. Spray carb cleaner in the two openings (assuming you have a T shape) until it stop comming out black
3. Refit

Oh dont worry, googled it Is it worth checking the WOT switch under the throttle body too?
