Faulty ISV symptoms

[raks.2008]

I have searched all the ISV threads and no where does it state problems that are related to the ISV. I have a 16V KR and the ISV buzz's when the ignition key is turned, but when the car get warm it regularly cuts out when the revs drop.... Does this mean I have a faulty ISV? I did clean it with petrol as learnt from a thread but didnt work...

yes isv can cause cut out, give it a clean with carb cleaner there's load of threads on this also overrun cutoff valve can be a cause, aswell as isv control module

do a search for 16v cutting out or 16v idling problems

Blue temp sensor might be worth checking aswell

Not on a KR.

If I had read the thread properly I would of known its a valver 

But saying that dont these pose a problem on valvers aswell?
