I have news. When i unplugged cable of MAP and Oxygen bank 1 sensor (both of same time) rough idle gone, engine run perfect. If i connect one of them ( just map or just oxygen or both of, 3 case do same thing) rough idle come again. Is it tell any story about broken part??
Thank you.

(cylinder compression test is fine.)
