when I try to start my infiniti 130 I must depress the accelerator to start it on 2000 Infiniti I30

If I do not depress the accelerator it just keeps turning over. I replaced the air flow mixer sensor and that has had no effect. When I start the car the automatic choke is working and the car operates OK. The only other related problem is that the car hesitates a bit under it is warmed up.
