I bet it was the TPS, that happened to my car when the car can not sense where the throttle is so it doesnt know when to shift, how much fuel to inject and stuff like that, try unpluging it and pluging it back in.

check your spark plugs. My car was running on 3 cylinders for a while.

This happened to a friends car, he got it scoped out and they said it was the mass ait flow sensor so he replaced it. Has way more power than it did before and runs fine now. So maybe trying replacing that sensor.
