2001 Dodge Neon

Earlier this week, my Neon's engine all of a sudden started to race when I started it, as if I had my foot on the accelerator. It would do this for several seconds, then calm down a little but still high. My car would move forward on it's own, I don't have to use the gas pedal. It goes slowly but steadily up to 45, at which time I braked. Friday, on the way home from work, the check engine light came on, the car started to jerk and there is a rattling noise under the hood. I took it to Auto Zone and they hooked up a hand held computer reader and it came back with codes of P1299 and P1281. I looked around and found somew general info on these codes. The 1299 code may refer to a vacuum leak and the 1281 indicated that coolant temp was below normal range. Can anyone here give some more detailed info, such as what part to replace or check? Thanks!

Wouldnt worry about the temp gauge code just yet chrysler vehicles set that code sometimes for no reason though it code be a thermostat stuck open as far as the engine reving up I would say you have a major vacuum leak or a malfunctioning throttle cable or related components I would listen under the hood for a hissing noise and try to pin point where it is coming from I would say that your drivability issues are related to a vacuum leak
