I read somewhere that that could be a boost leak if its reading at that? Not sure tho! Iv got a autogauge one to fit when I get a pod for it, how easy was it to fit?
Could be as my next job is to sort out the PCV and fit a catch tank. It's probably some where in there that's leaking.
Very easy to fit. The A pillar cover just pulls off. When you fit the nomad you just drill a hole in the top fitting for the standard cover and stew it in. It's a bit of a pain running the wires through the dash but it doesn't take long.
