I have a 1996 Oldsmobile 88.

What is your question?

today I was driving to work and passed someone while pressing heavily on the gas. I looked in mirror as I passed the person and saw white smoke rolling out of exhaust. About 45 seconds of smoke and it went away. Shortly after I was at my stop and went to pull in and noticed my battery light on and the steering got very tight. I parked and got on bus. What the heck happened?
