Default seafoam..high idle

i seafoamed my car today and for some reason my engine idles around 1400 rpms when i shift the gear into neutral and stays there for about 10 seconds or so...has anyone else experienced this problem, or is it normal after driving it the first time after you seafoam it?

Your IAC may be dirty, you should clean it out and while you've got it off... You should do the IAC Restrictor Gasket Trick!

The IAC trick isnt going to solve the problem though.
