new injectors- whats the problem now?

So I just put a new set of 175's in yesterday and when I have it in park and slowly raise the rpms, between 2-3k it starts to miss and when i let off and it comes back down it drops all the way to about 800 rpms and then has one last little "hiccup" almost then returns back to normal idle? Anybody have an idea what this might be? A little more information- it has been driven for at least 100+ miles so I'm thinking all of the air should be out by now right? Also, there is no miss driving down the road whatsoever, just when its in park. Thanks guys...

Are you sure your Boost/MAP pressure sensor vacuum line is plugged in? Any lights or codes?

No lights or closed and if I go WOT with it driving nothing happens... no miss, no stutter, no hesitation, she just goes all out.

^ sorry yes the vacuum line is plugged in too... maybe it just needs a little more time to clear up like 7.3 said?
