thanks

If the engine is a 2 Litre type as fitted to the vectra, then it could well be the Ecotec value. They have a tendency to get 'coked up' and can be cured by buying a valve gasket from Vauxhall (Less than �1)! and a tin of carb cleaner. DONT be suckered into buying a complete new valve, they are around �115 - 120 plus vat!
had a friend with a vectra with similar- first time vauxhall charged 300+ but is a valve unit that can be cleaned out as kris said. i did it for him after about once a year.
