Hi I just noticed the other day oil slightly misting out of the breather on my valve cover and the oil cap, changed the oil cap gasket and I haven't seen much build up around it but it's still coming out of the breather, usually after wot I'll notice it more. And to top it off I got a p0505 code idle control system, my idle has been weird sometimes it will drop to 500-850 and oil light flickers then it idles at 1k. Now just yesterday I was on a 800 mile trip and noticed it almost sounds like its skipping at idle and when I take off it sputters until I get going and it's not to noticeable at a steady speed. Boost dropped to 18psi now at wot instead of 24psi, where should I start and any suggestions on what could be causing any of the above, car has cams and exhaust, everything else is pretty much stocl, forge bov, fmic, tuned at 24psi by jr and it ran fine for about 2 months now all this happens

 

sounds like a vacuum line popped off.
