OK so today I finally had a few minutes to do some diagnostics. I hooked up the OBDII to it and I found my short term fuel trim +25% shortly after starting it and lightly holding the gas (1800-3000rpms). IIRC + means the engine is running lean and its adding fuel. My next step will be to swap the O2 sensor in hopes that the one I have has gone bad. Hopefully I'll at least be able to gather some information from it while I have it out.

Fuel pressure was find a few days ago, and I don't see a reason for it to be low while warming, but OK while hot.. AFAIK my cat is working fine, so I don't think its too much back pressure. Could it be my SAS pump is cutting off early?

If you're not driving it "like its stolen," are you really driving?
