I'm having issues again. My first though was that the large clear tube(dunno the name...boost reference hose maybe?) that runs to the intake manifold had blown off again, but it has not. The problem is intermitent, sometimes no power for minutes, sometimes on and off a half dozen times in 3-5 seconds. Other times it runs like normal. It's also running just a hair rough.

Any suggestions?
