ATTENTION!!!! HELP!!!!!!

i have a s13 with 95 ka in it. car idles perfect. when its warm and i come to a stop and try to take off again my engine sputters like crazy. and when i take it past 4500rpm it stops trying to go faster and just makes noise.
This is not typical of this motor it has always worked good for me and i have had it in 4 of my cars. and the motor has been my daily driver since summer. i am thinking shitty injector.
When i unplug my maf it completly dies out. the car had a bad idle problem when i put it in idled at 1500 all the time. i dialed back the idle with the iacv and worked good sinceā€¦ any ideas?

Shitty injector or fuel pump? i had the same problem.

Check the plugs

fuel pump. just had this problem. fixed it with a working pump.

fuel pump, foul plugs may be contributing to the sputter, but the fuel pumps the causeā€¦happened with my old KA as well
