Message Basically my z spontaneously started not starting at normal rpms. Always used to start right up and then I parked it got back in an it wouldn't start. the battery started to die and the starter began to slow and finally it fired up. It will crank at usual starter rpms forever and not even come close to starting now.

It will start at very low rpms. Basically, engage starter, disengage starter, as engine falls to zero tap gas... starts.

known issues: passenger side o2 not working. have replacement and will try to do this weekend.

Is it at all possible that this whole problem is a crazy fuel trim value because of the bad o2 sensor?

Otherwise car seems to run fine. I have a single wideband on the driver side and that one reads fine. On hand I also have a spare dampener and FPC. Any guesses on the likely culprit?

Putting AMS garbage, and $500 ebay wheels on a Z is like
dressing a Victorias Secret model in a Walmart dress and
Payless shoes. You're embarrassing yourself.
