Dave W,
Thanks for chiming in! I ran the EEHack analysis myself which is how I knew the PCM was adding as much as 17% extra fuel. I was wondering if this is common on MAF equipped cars on E10 fuel or if maybe I have an issue that some preventative maintenance might solve? I think the thing to do is install my new O2 sensors and go for another datalogging drive. I also think that I should clean the MAF. I can see the MAF values changing, but if they are lagging it could explain the hesitation I've experienced and high fuel trims. I'll do some work and report back.
