Right I changed m pcv today also took dv out and clean and checked it its perfectly fine as I only replace a month or so ago car starts and runs fine cold then when warm you can feel a slight judder on idle but rpm needle does not even move, when Drivin it's perfect can now feel the pcv was naffed as it goes like f#*k , i unplugged the MAF too and drive a couple of miles but car runs the same as when MAF is plugged in any one had any similar problems
