I have did a search with no real answers, i have a 2012 dyna, with check engine light and a p0507 codeP0507Idle Air Control System RPM Higher Than Expected , i replaced iac motor on throttle body,(it was making funny noise, anyways not problem, i have checked throttle stop screw, was able to back off to lower throttle and loctited it , was fine for a day, and then idle kicked back up and C/E light back on ,checked terminals on battery and are tight no melting issues, what can i possibly check now frustrated,

 

check terminals on iac and ecm and tps, also if you havn't check both ends of the ground cables to make sure they are clean and tight
