Q: Car stalling and then accelerating while driving

My car has begun stalling while I am driving. I was told to make certain that my transmission, power steering, and coolant fluids were all at their appropriate levels. I did this and the vehicle ran fine for several weeks. Soon though, it started stalling again, stalling about five times in one mile. It also tried to accelerate without my foot on the gas pedal. I've also had issues with my turn signals. My left turn signal is blinking really fast, which I was told indicates that a bulb is out.
