99zx6r will not idle
 

My 99 ninja will not idle I have played with the token in gas and replace the plugs I replace the coils and I don't know I have to keep gas on go and then if I do send it to her titles then it won't start and I have to back the gas all the way up off but the choke all the way on any suggestions on how I can fix it or why it runs good once it gets going
