My wife had a key made and the first time she used it it got stuck in the ignition, so sometimes it's hard to tell of the ignition is off. Well the other day I went to start it up and the ignition was left on, so the battery was down where it just clicked. I let it set a few hours to recover and it started. I though I would leave it run to charge the battery, well I forgot, maybe a pre-senior moment, a day and a half later we were going to drive somewhere and I noticed the idiot lights on. Oh no I thought the battery is dead again, but no, the car was nice and warm inside and still running. It idled away half a tank of premium gas between Wednesday afternoon and Friday morning.

The map sensor went bad, so I repaced it and added a silicon diode in series with the reference voltage, it dropped to from 5vdc to 4.3 vdc. The map sensor reading wot went from 14.65 psi to 13.05 psi. I estimate the ignition timing advanced 3 degrees. It stays in closed loop during wot at operating temperature, but takes some time to warm up as it now hesitates when cold. Oxygen sensor 1 reads .045 volts during acceleration when not fully warm and normal readings when cruising. The ultragauge needs to be recalibrated now. When the map sensor was bad it read 1.6 psi continuously, and the ultragauge read 230 mpg! Timing was 34 degrees.
