Odd idling issue with my car.

I've had an odd issue with my car lately with it's idle, when I first start it idles fine, when I go to back out in the mornings as soon as I turn the wheel the idle drops down to almost stalling, but doesn't stall, soon as I give it gas though it's fine. It does, however run fine while driving with no problems.

I've also had a few instances where the idle would get a little rough at a stop sign or red light, but lately it seems to happen more-so when I turn the wheel. So far it just seems intermittent, but when it does, if I give it a small rev it seems to fix itself, or if I put it back in N it goes away as well.

I had a CEL light for awhile, and just recently had some vacuum leaks fixed, and the CEL no longer comes on, so I don't think that is an issue, unless they possibly missed a leak. Is it possible that the IAC could be going bad at this point, or maybe something to do with the steering pump?

Any suggestions you have would be greatly appreciated.
