Car dies when going more than 5mph!

[Aimster]

The other day I got a service engine soon light on. The problem was the intake camshaft insensor.

I drove about 150 miles with my car and then suddenly today it disappeared. Cool! I park my car run inside for an hour come back outside and start the car.

I accelerate to go up the hill and the car dies. I restart the car and it dies again when I accelerate. Kept doing this. When the car died I got the service engine soon light , battery light and some other light next to the battery come on each time.

Now.. just before all of this happened (before any of my problems) I put some fuel injector cleaner in my car. The fuel was full as I just filled it up. I only put about 1/4 of it in the car. Could this be the cause of the problem?
My roommate said if I reset the computer it should be fine. So.. how do I go about doing that?

Thanks in advance.
