Car idles erraticly between open & closed loop

Hi all

I took apart my intake and cleaned the filter, I put everything back together tightly (used carb cleaner on the intake as well) and now, it idles fine when i start it, but for about 1 minute between being cold and hot (just as the car is warming up) it idles up, down, up, down, etc etc until the temp is warm, then it idles fine...any clues?

clean your maf and/or take TB off and clean your IAC. Make sure when you clean the maf you dont touch the sensors, just use TB cleaner and the little red plastic nozzle. Let us know.
