thanks lads for the info on what might of been the problem i changed the inlet manifold not bad price £190 next day delivery it fixed the problem a chewy job but worth it in the end the manifold was totally seized up the swirls where jammed open a proper job stripping the engine some plonker designed the engine with a stud behind the fuel pump but probably a good idea for vauxhall as you have to remove the pump also cleaned the egr our lass dosent collect that much crap in the hoover a month but as i said a big thanks for the advise
