vauxhall vectra 1.6 1998?

Thankyou for your reply gtwannabe i have tried your suggestion of the small vaccum pipes & they seem fine ,as stateted before the car runs perfectley when cold but after 5 mins when warm the car still drives smooth ie no juddering but the engine seems to bubble & lose power this is more evident when engine is under strain climbing a hill, if it was an older car i would say the choke was left on as it seems to use more full & a strong smell of fuel from the exhaust any more thoughts many thanks.
