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
