I just got my st185 engine rebuilt and I didn't really get to drive it much before that. And know I hear a kind of buzzing noise from the sensor that I think is the map sensor (located near where the wire loom enters the interior) I also noticed that the thingy that adjust idle is vibrating at certain rpms.

Is it supposed to have a noise or is it broken or do I have vaccum lines hooked up incorrectly

I think that's the AC idle up valve you might have the vacuum lines hooked up backwards. Don't quote me on that I might be wrong.
