89 swift

I have an 89 swift with a 1.3L 4 cyl. SOHC . The check engine light started coming on and it acts like it's fuel starved. There are 2 vaccuum connectors snapped off and i'm wondering if this could be the problem. They have been broken for about 9 mths now though. I haven't been able to get the dealer to order me new ones and i haven't found any at the wreckers yet. If anyone knows what might be wrong i'd love to hear any suggestions.
