Tried to drive the Miata in to work today, and it suddenly died. AFRs went full lean, then it died. I was logging at the time, so I can post any log data.
No nothing obvious. It doesn't seem to be a lost sinc, since the count was 0 until after the afr went full lean.
This sounds stupid, but it might be just it of gas? It didn't sputter though. My empty mark might have moved after changing my gauge faces. I have a friend bringing me some gas
Aaaaaand it was gas. I ran out of gas. Like a dope. 1/8th tank is the new empty.
Heh. I know someone who brought his new race car to the track for a test day, took it out, spent an hour debugging "misfires", gave up, towed it home, dropped it off at his mechanic's, and then paid for 3 hours of labor to diagnose a car that was out of gas and had a broken gas gauge.
Oh man, I hope you gave him a hard time for that one. I feel lucky I was logging. I would have checked a bunch of other things first otherwise. Seeing the AFR go max lean in the log before any other events combined with a pump that was still priming was a strong indicator.
I cam fairly close to doing this in my NB. My NA only takes 9.5 galons when the pointer has gone past the empty line and is pointing at the top left corner of the E. The NB is out at the line... I was just a smidge above it when I filled up the first time and took almost a whole tank of gas...
Why do you guys let your tanks get so low? I killed a DW400 on my supercharger Mustang a long time ago, and I suspect it was because I always ran the tank to almost empty before refilling.

Because the Miata has a tiny tank and mediocre fuel economy? This was the reason I drove my S2000 up to 50 miles with the gas light on regularly. Otherwise I would have been filling up everyday.

Because fuel is heavy, dude.
(Actually a semi-serious answer here -- most serious autocrossers will run with just enough fuel to keep it from starving in corners, because that's 60 pounds of weight they don't need to carry around the course).

Why am I stuck on the side of the road?
