Declining gas mileage 04 V70R Topic is solved

Update: Changed the plugs and upstream O2 sensor. No change at all with the declining mileage. Also seem to have an over-boost situation going on now. Not sure what to look at next, but have to get Vida set up.

I wanted to update this in case anyone checks it out. As stated, plugs and O2 sensor made no change. Yesterday I rebuilt the PCV system after failing the glove test. Not completely blocked, but pretty messed up. Took it for a good test drive today. Mileage went from 22 (before repair) to 29.3 mpg. No AC on. Nice. Oh and I fixed my over-boost situation with some Seafoam through the brake booster line. Runs smoother than it ever has with boost right where it should be. Now for the new e-brake cables...

Vida needs a patch file now, the internal clock is set to expire Dec 2017.
