i was driving my s13 with sr20 turbo around the other day and i stopped at a stop sign and my car went from 1000 rpms to trying to cut off what could it be? and it does this everytime i drive it but cranks and runs fine until it warms up

You need to play with your idle air control valve adjustment.

If you adjust your throttle plate screw and IACV together for the best possible idle you will find it. You just need to spend some time finding the optimal placement for both of these.

Don't forget to make sure to check your ignition timing at the CAS with a timing light as well, before doing these
