Got the Walbro in, Fixed it!
So I had a lean condition:
Replaced plugs, Wires, and installed an adjustable FPR, and still no-go.
Dropped in a walbro 255, Worked like a charm, fixed the lean condition in the higher RPM.
Sounds MEAN too *The fuel pump*

Re: Running Lean, nearly stock, wtf.
I have a walbro in my civic and I never hear it.
Now I wonder if the cx pump just doesn't flow enough or if it was dying.
What kind of afr's are you getting now? I have always wanted to put a wideband on a stock ecu car, but I have only had one on chipped ecu's

Someone else had told me the stock CX pump just doesn't flow enough (And I have a 92, so its the odd-ball/first year)
AFR's I'm getting consistent 13.8-14.2 under load (Including WOT) all the way to redline. in gear, no load, jumps to 16.0-16.8 typically.
*GRANTED, noone has showed me how to CALIBRATE my AEM UEGO because I tried reading the manual and it was WAY over my head, BUT I bought it used, so it was calibrated at one point for an Integra LS*
The main reason why I used the Wideband to help diagnose this issue, because accurate or not, I shouldn't have been 'pegging lean' at 5700RPM
