Default What effect does vacuum leak have on engine performance...???

Will a vacuum leak cause much loss of performance
and if so is there a way to estimate how much per inch of vacuum or anything like that...just curious think I had a good vacuum leak from my intake manifold being loose.

well first i suggest fix it and go drive it and see for yourself, but any amount of unmetered air can really f'up the air fuel ratio and will definitely cost power
