very harsh idel wiht 840cc injectors

[moonshinekouki]

so i got my s14 with rb25det series one with:
aem ems
840cc
gt35
44mm waste gate
it made 501 whrp at 19 pounds.

now my issue is that regardless of cold/warm start i cant get it to idle unless i have to hold the gas peddle down for about a min then it will idle amazingly at 1100rpm thats pretty damn good for 840cc injectors.
any tips of what i should be checking out to see why its doing this?

also does anyone know why the aem if u go lock to lock with the steering wheel the car stalls out is it becuase the ps pump goes on and off?

thanks for hte help in advance.
