rough idle

[MN94ProbeGT]

My car is idling really bad. It drops below 500 then raises to normal then drops. Its like a muscle car but performance has not been effected. Im getting nothing but problems right now.

JUMP THE GROUND AND TEN PIN WITH THE IGN ON BUT NOT RUNNING. YOU SHOULD GET A CODE 34 THREE LONGER FLASHES AND 4 SHORTER FLASHES.
CODE 34 IS A IAC MOTOR/VALVE ITS DESIGNED TO REGULATE IDLE WHEN UNDER LOAD IE; AC OR HEAT ON MOSTLY ANNOYING BUT LEFT THAT WAY MAY FOUL PLUGS

no code and ac or heat was not on when running the car. Is there someway to check the spark plugs??

I have a nice crack in my pcv valve. My car stalled on me and i was like wtf? I check under the hood and i heard this pssssss sound. I look at the pcv valve and the top half is popped off. Luckly nothing major.:)

the iac valve doesnt only work when the ac is on it is always monitoring idle and adjusting it
