It would really help to know if you had an automatic or manual.

How high are you reving it up? And Are you reving it up in park or in neutral?

the throttle cable may have some sort of obstruction or may be too tight I had a similar problem and it was easily fixed by loosening the cable. Other than that I guess it could be IAC sensor or TPS sensor.

in Neutural.....sometimes when i go down a really steep long hill (3km), i would put it in neutural and coast down, at the bottom i would forget that its in neutural and hit the gas to go faster. the revs go well into 6000, and it takes so long to come down, but i dont think its the cable, it doesn't seem tight.
