To help (and thanks so much btw!) I have a narrow band regular o2 sensor in factory location and a wideband for turbo tuning (lc1) at the proper place also
i generally use the gauge on the narrow band just for monitoring idle and that sweep as well as to keep track of the narrow bands health but for most/all things tuning i use logworks but later tonight i am going to recalibrate it just to make sure something isn't up with something else and my narrow band is actually reporting a valid problem... \
I drove it a few minutes ago.. and it really has super slow acceleration in comparison to when it was healthy. (didn't drive far but far enough to tell..)
so i guess i have to find out and prove its timing for the lack of power and i guess secondary - why my narrow band doesn't register anything but maybe 1 bar of red (yellow stoich to green ) Would a bad o2 sensor cause the lean?
i am almost positive they aren't dependent issues on each other is the good part i think.
As far as vacuum hunting.. my boost gauge shows normal on the vacuum end - i have gone through almost all of the topside vacuum lines and don't see anything or hear a leak - i pulled one of and the engine rapidly stumbled until i put it back.. also usually when i drive and hit 0-1 psi of boost and shift ill hear a vacuum leak if there is one.. its a very distinct sound.. i didn't hear that this time.
_________edit + additional info
Ok so I marked all the pulleys I and E and turned the crank by hand and it indeed is off 1 tooth on the exhaust cam- so mystery solved there. It still makes a "chushing" sound when turning over but i bet that is what that noise is. (ie its/engine running and from the water pump area there is a chush sound... er there also is a random 1 or 2 per minute metalic whine too... i think i got screwed on this deal lol)
So once I get that fixed... I bet I can replace the o2 sensor and maybe get that part "true'd" up and better investigate the lean a/f on narrow.
BTW I used guides from this forum to get most of this done and suggestions from you guys directly to motivate me in the right direction. Thanks again
Ill update Tuesday - thats when Ill redo Tbelt.
