Intermotor 14847 Idle Control Valve

I bought this idle speed control valve ( Astra mk3 C16se engine) fully expecting it not to work very well as some cars are very fussy and ONLY an Original Spec/ factory part will do ( Jap cars esp) .... I have used Intermotor parts ( they have a factory with R+D so that’s good) in the past on older tech cars and they did ok ...this sensor is a key part and car stalls a lot or won’t tickover/ idle properly if it’s dirty or faulty but the gamble paid off , In fact it worked very well!!! Considering it’s super cheap price. Sometimes it’s worth taking a punt in spite of what the doomongers say BUT be prepared to spend £60 plus if problem is hard to resolve :-(
