Can I get pics of the fuel pressure solenoid? Maybe that would explain my unstable fuel pressure bouncing between 30-35psi when I hit the gas. Would that explain it? A bad connection, or something? Or is just my damn fuel filter, which is the only part which isn't either brand new, or has been replaced..

well I have too many codes to count 
but it ran the exact same the day after everything was removed as the day before... including the EGT's.
no wideband.

oh damn great info! I know my car has been running lean up high, no wb yet, but pullin o2 sensor and plugs it looks that way. I'm gunna go look for that solenoid tomorrow and plug it back in and see what happens. I'm only hitting 10psi max in the high gears and have a walbro, so i didnt think i should be runnin lean. Maybe this will be a simple fix.

Another thing you can do... just plug it the FPR to the manifold. I believe the only thing the solenoid does is disconnect the FPR from the manifold during starting to give slightly higher fuel pressure when starting the engine. Most people who run aftermarket (so I hear) run with the FPR connected directly to the manifold (per ReTed's instructions to me regarding setting up my Haltech when I get it - so don't take my interpretation as gospel - its how I understand it to work). So maybe it will hurt a stock setup when starting to wire it up this way, but I dunno. Once I get the haltech in it will certainly go straight to the manifold though.
But I also have a fuel pressure gauge and a wideband so I'm gonna keep a sharp eye on everything.
