Default Poor Idle and Vacuum

I just replaced my 2002 corolla engine with a junkyard engine from a 2003 corolla. now the engine runs rough at idle and the brake boost doesn't work at idle. it sounds like a vacuum leak or poor vacuum. Any suggestions?

I was looking on another forum and I found out that my serpentine belt was too tight. I had used the tensioner form the 2003 and it was a little too tight. I guess I should have known.
