1987 toyota tercel oil leak? high rpm problem

Hi, I have a 1987 toyota tercel 4 speed, hatchback.
When i went to get the thing smogged, they said that the RPMs were to high.
So when they went to lower my RPMs it would stall , or just about stall. But then when they would spray it down with brake cleaner or something, the rpms would jump up from the "almost stalling position", and then they said that it was because i had a leak somewhere? Does anybody know what they are talking about? Can someone please point me in the right direction, in either fixing it my self, or the cheapest posible way to go about fixing it?
Please let me know, I need to regester my car:(!
Thanks,

I don't even understand the question. Was the check engine light on?
