Extremely rough idle, flashing SES light etc...

I replaced the CCV's and that didn't solve it. I'm thinking either a vacuum leak from the valve covers or intermediate lever problems (valvetronic). I can't wait for 60 plus degree weather so I can actually start tackling some of this stuff little by little.
