My car kept dying when I stopped, then started making weird noise & now won't start? Oil light is on?

It 0 degrees where I live, & I only bought the car 4 months ago. It is a 99 ford taurus, I bought it for 800 on craiglist. I brought a mechanic with me to check it out n he saw no other problems besides a small antifreeze leak and the gas gauge being broken.
I'm not out of gas, I filled up today. I could start the car a couple hours ago, but it died whenever I slowed down and at every red light. I finally got it home and as I was pulling in, it died again, and when I tried to turn it on it made a different noise and wouldn't start for longer than 2 seconds before the oil light goes on and I can't press the break down. The engine also started making some sort of knocking noise out of nowhere as of yesterday.I'm having a friend mechanic come look at it but he isn't off work for two more hours. What could this be?

I want a car that is fuel efficient yet stylish, so please leave any suggestions from the cars listed above.

My '06 Ford Taurus is having what i'm assuming transmission problems, any ideas?

The other day while attempting to back up a small slope, my engine revved up and a message came on the info area of my dash saying to check the transmission. I turned off the car, turned it on and the check engine light was on. I go home and check the trans fluid and it's full. The next day I start my car and the check engine light is off, but now my car shakes on heavy acceleration and gear changes. I'm not a car person. Any ideas?
