Focus idle problem

[Six6siX]

Mate has a 1.4 Focus that has recently developed a dodgy idle.

Whenever the clutch is dipped when coming to stop or stationary, the idle dips and sometimes cuts out.

Its pretty intermittent though - sometimes it goes days being perfectly normal.

Likely culprits?

Its a MK1 as well.

Imy that sounds almost exactly as he described.

So the idle control valve - expensive/difficult fix? DIY-able?

Cleaning the icv? What with?

That's a good point - I'll get him to have a check around for any bad hoses/leaks.
