Default only when its cold

i have a problem in a camaro, when the weather its cold the engine have a failure like a vacum leak and even intake explosions, but when the engine warms the failure goes, and when the weather its not so cold the cars runs good, i went to autozone and the scaner show lean mixture in the O2, so i sprayed the engine and nothings happend, and i cant see or hear any vacum leak then i clean the maf sensor, TB, IAC, but the failure still there, could be a O2 failure? low fuel presure? temperature sensor? im so confused... i have about a month whit this thing and i hate them

I say you have a vacuum leak. The Pcm is not really looking at the O2s until it warms up and goes into closed loop.

I take it you have a gauge hooked up. If you do cycle the key from off to on 3 times waiting about 2sec in between each cycle and see what the pressure is.
