vauxhall vectra 1.6 1998?

paul diagnostic machines are only as good as there operators i am afraid .even if there are no fault codes a half sharp technician should be able to diagnose your fault by checking specific values associated with different sensors /carefully check the small vaccum pipes at the rear of your engine for splits especially the pipe that leads to your fuel pressure regulator before you do anything else after that try another garage
