Hi GVK like your comment on the rover lol and i did have 3 of them , The scorpio as now had a throttle position sensor , fuel filter , fuel pressure regulator , fuel pump , plugs , leads , cap , coil , cleaned everything else i can think of and ive checked pipes but cant seem to find anything . Im now thinking do i strip inlet manifold etc and put new gasket to rules things like that out or would it be those air box meters even though them seem ok or will it be a injector . Im just getting nowhere and starting to run out of things to try
