hard starting when car is warm

[redberkeley92240sx]

Whenever i go to start my 92 240sx the idle jumps up as it should but then it drops to like 300 or 200 rpms and the car feels like it's going to die for a second or two, untill it corrects itself back to 750 rpms. This only happens if the whether is warm or if i had been driving the car for a long period of time and i shut it off and start it up again. (basically when the engine is warm.) Can anyone shed some light on the situation as to why this is happening or what i need to replace in order to get it fixed. Thanks
