Rpms are running high engine revs up to 2000-3000 rpm in park and neutral and when driving I don't even need to put my foot on acclerator and car speeds up a little more by itself causing me to have to hit the break. Had my trany rebuilt 6 months ago and they say nothing is wrong. Help

Do you
have the same problem?

The transmission isnt going to cause a high idle. Have you checked for codes yet?Also have you checked for a vacuum leak? Clean out the idle air control valve and throttle body.
