Low RPM code with IAC?

[UB2 SLOW]

My car keeps giving me an IAC code that says my RPM's are low. I have a new one installed and it still gives off the code. Also the car is slightly missing. Can this also be caused by the IAC code?

Thanks for the help! Looks like I will be spending some time in the driveway.
