Default How do you adjust the "rolling idle'

Ok i finally got my idle situation figured out... but now everytime i take it out of gear it revs the motor up to 1800 rpms while rolling down the road. What should i do?

look at the cable that goes from your accelerator to your t/b and there should be a screw in there that you can adjust.. mine was keeping the butterfly part open causing it to revv up to 5k and stay there.. thats how i fixed my prob, hope this helps
