It's likely that an unconnected vac hose is compensated for by the engine management by giving more fuelling. In certain circumstances, like when coming off boost, the engine may go very rich. You may end up with your "Check Engine Light" (CEL) coming on ... Unless a previous owner pulled the bulb? Just connect up the vac hose as I described earlier and you'll be fine. Don't go blowing flames at the chap at the smog shop - he'll laugh at you :) Paul 1989 900 Turbo S > On Apr 14, 9:18 pm, Frank Vuotto <> wrote: >> On 14 Apr 2007 16:15:33 -0700, "robertjm" >> >> <> wrote: >>> OK, so I finally figured out where the bypass valve was.
