Oil tank sensor on my 90 Opti failed, and thought the tank was empty. It would beep, one long beep, then cut the rpms back to max of 1500, and running rough. Every 3 or 4 minutes it would beep for about 5 seconds. Dealer replaced the sensor under warranty, and told me that the motor runs extremely rich to provide extra cooling/cylinder lube when it thinks it's not getting enough oil, as well as limiting the rpms to 1500. (Actually s'posed to limit the rpm's to 1200)

My motor has a whole set of beep codes that can give you a clue as to why it's messed up. I have analog gauges, not the Smartcraft, or it would just tell me what's wrong.
