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!
have the same problem?
