The oil light comes on when ever I stop at a light or stop sign then goes out when i let off the brake and accelerate. The motor doesnt run any different when this happens but its really aggervateing.Also I was told that the massive airflow sensor was bad and the 02 sensor could either of these cause it. :?

The mass air or the O2 have nothing to do with the oil light. It is a sensor thatlight a dash light when you have less than 7 lbs of oil pressure. The problem is;

1. Low on oil
2. Bad oil pressure sending unit
3. Bad oil pump
4. Bad engine bearings.

Good luck

Suggested Repair

The oil light is unrelated to the mass airflow or oxygen sensors. Check oil level first, then the oil pressure sending unit, oil pump, and engine bearings, since the light indicates oil pressure below about 7 psi.

Conversation Summary

A 1993 Ford Taurus oil light comes on when stopped and goes out when accelerating, with no change in how the engine runs. The owner asked whether a bad mass airflow sensor or oxygen sensor could cause it. The expert said those sensors are unrelated and that the light means oil pressure is below about 7 psi, pointing to low oil, a bad oil pressure sending unit, a bad oil pump, or bad engine bearings.
