idle is jumping around???

[Hanz41]

so my s13's idle especially after being warmed up is jumping around.. the jumps around from like 1000-1400 rpm's and sometimes its worse and sometimes its completely fine, and sometimes it very suttle change in rpms like 1000-1100 and back and forth.. this is a sr20 redtop btw..

I appreciate your time and help, thanks

im guessing its a vacuum leak but i took a can of carb cleaner and sprayed it on the vacuum lines that i could find and nothing came up.. i def could have missed a line though

i have the same problem but i have a radiator leak and when my car is low on it fluid and hot it idles high around 1k 1100k but once my car is cooled down it goes back to 700 idk if this helps it might lead u to a fix maybe LOL
