They were hitting -25 STFT but there was alot more to it. I got it sorted out. On reset of the PCM it resets the FPCM also and fuel pressure runs at 65 psi at idle(and all conditions) until it relearns. Once it "relearns" fuel pressure at low load is 50 psi and the fuel trims come back into line where they belong.
