i have a 91 s13, DOHC 5 speed. started acting up last night. when i first start the car it idles fine, but after driving it for a while it wont idle. if i let off the gas or stop, ( in neutral). it will immeadiatly die, or idle down to like 100 rpm, then back up to 900, then back down to 100 ect.... it will keep doing this till it dies, or i give it some gas. it also seems to be popping more on decel (3" open exhaust). any help will be appreciated.
