    Rough idle, stalling on my 2000Expedition. Code came up as PO171. Found a leak in my PCV hose at bend. This is a Ford only part. Went to local Ford dealer and ordered the hose with the PCV valve included. Replaced it myself. Problem solved.Ford part # 2L1Z6758GA.

    I had extremely rough idle and most of the time it would not idle. I replaced the PCV plastic line with rubber hose. It has fixed the problem.
