High Idle!

A week ago, the jeep idle fairly normal.. I sprung an O-ring fuel leak at the Fuel pressure regulator, after replacing a couple O-rings, It now idles extremely high.. 1800-1900 rpm.. and will NOT kick down no matter how long you let it warm up..


I drove it like this today, if its in gear, its choked down to about 1200rpm.. but the second you park.. right back up.


Who can guess what i screwed up :helpme:
 
I have the Ford yellow top injectors with New o-rings, installed roughly a month ago..

I dont *think* its injectors.. But regulator sounds possible..
 
Check the FPR vacuum line for fuel leak. Get out your volt-ohm multi meter and check the TPS voltages, and the grounds.
 
... the regulator or the fuel return line!

I was thinking fuel pressure test, because of the leak... crushed return line?
