My ford f150 is running at a high idle its starting cold and runs as high as 2500 rpm it will kick down to like 1200 to 1300 rpms I cant find a vacuum leak. I changed the air idle control valve to tell you the truth it seemed to make it worst. In gear its running at 1100 rpms I don't wont to be a parts changer what do you guys think could be causing this problem. Other than that the truck runs great no misses lots of power and no check engine light.
