Next, if you remove the PCV from the system, you don't get oscillations in your rpm from 1k to 2k. All the PCV does is vent the extra pressure from the crankcase back to the intake. Check that, it's a one way valve and will not cause oscillations like you're describing unless you've got a vac leak. Check the FSM if you don't believe me.

dude it will oscillate like that maybe not as much as i said but it will if that hose rips in half (the one that connects the intake manifold to pcv, creating a hole in the manifold) it varys from engine to engine, it happend to me on a 5SFE, CA18DE, SR20DET and 3SGTE.

Yeah that would happen if the hose ripped in half cuz then you're talking about a massive vac leak. Seriously, put a vac gauge off your fpr and cut pull the hose. You'll see your vac go nuts. Hence why I was saying it's probably a vac leak.
