My idle (usually when warm) is getting a bit excited. Up and down 1200 maybe 2000 rpm and hunting about. Doesn't seem to be an air leak, doesn't seem down on power. Maf disconnection makes no difference. Scan has loads of things it isn't happy with maf (where I unplugged it i suspect) idle valve and some others but I suspect that is one thing upsetting others. Pcv and dv never changed on 58. Also may be imagining it but turning the car on and off again would sometimes reset it. Suggestions please.
