Default Esc cos (Small Turbo) idle fault

Hope someone can help with this one!

I have an intermitent idle problem, basically the car will start, warm or cold with no problems, but sometimes will have a very low idle, almost stalling, which also sounds like it may have a small miss, after anything beteen 10 - 60 seconds there is a click (like a relay sound) from behind the fuse box, and the car will then idle and run perfectly

Thanks in advance for ay help

May simply need setting up mate, but alternatively, the lambda sensor and the MAF meter are common causes of problems like this.

Also, check the dump valve isnt leaking.

The car was set up at Power station in cheltenham, the co was very high but this was solved by cleaning the air flow meter (hot wire??), dump valve was checked and deemed ok. Haven't looked at the lamba sensor yet.

Have you any idea what relays are situated behind the fuse box?

Thanks again
