Error code P1518

(1999 Ford Escort)
in Uncasville, CT on February 18, 2014
I have an actron ODB 2 scanner and when I ask what the error code P1518 means it says Manf Cntrl Veh. Spd. Idle speed control Auxiliary Inputs. I have a Haynes Manual but the code isn't even listed. So I googled the code also and received a different meaning. Instead Ford Code reading online says p1518 means Intake Manifold Runner Control. Should I change the Idle Air Control Valve, IMRC, or both? Anyone have any suggestions? I cant afford a mechanic and trying to get engine light off to pass emissions. Thankx

That doesn't mean to change parts, it means to find and repair the issue that is causing that components issue.
