P0507 Idle too high

P0507 "Idle Too High"
I've been getting this code intermittently. CEL comes on after cold start once in a while, not every time. I can reset the code & all is good for a while.
Is this the Idle Air Control valve?
Has anyone had to replace it, or take it apart & clean it?
Thanks
