High idle speed in park ( no codes )
Had new intake put on vacuum hoses
changed out iac replaced even sprayed but
no leaks. Disconnected iac isles at 500
rpm plug in iac jumps to 3000 ?
I have no idea what's going on. Thought it
might be throttle body but it's new
Did you replace the seal with a the new seal? And there may be a vacuum leak with one of the hoses going to the pcv, and from the intake. Watch this video, its on a 2003 Ford Focus, but you'll get the idea on what to look for... https://youtu.be/gLXmr2TVUtg
There is still a vacuum leak coming from somewhere. New seal referring to the IAC.
