Would it keep you from reaching full power in an m6 car?

i turned my throttle screw back down(i know i houldnt have touched it to begin with) and my idle dropped just under 1k @ idle. my p0121 code went away. i think that dropped the actual idle just into the range that the pcm sees that it should be.
