Hi, all. I have done some checking on my foci, and cannot figure out what the issue is. I have an idle fluctuation that goes from 600-1000 rpms. When using any electrical it causes it to stumble as well. I have replaced all motor mounts, with motorcraft. Cleaned the maf, cleaned the throttle body, and still has rolling idle issue. Any ideas, or know causes for this? Also no codes come up on scan tool. I am kind of stumped.
