My bronco started idling at 1400 rpms. I cleaned to IAC valve and butterflys with carb and choke cleaner now it idles at 2000 rpms. Cannot find a vac leak no loose connections what can I do

Hi bamapearl and TY for the donation

If the IACV and passages is thoroughly cleaned out-inspect for a sticking throttle plate and kinked cable to include testing the throttle position sensor. Check the IACV if its moving in and out
