is it possible for the o2 to lean the car out enough to make it stall until it gets hot and wont set off a check engine? Or do i rip off my intake manifold this weekend and see what happens

Something happened before this issue started from the sounds of page 4.
Please confirm that all was good before that large curb.
On my 97 SSEi, recently I was getting a lean bank continually and trying to determine what was happening. The car can dump fuel in an effort to correct a lean condition. A fuel pump, strainer and filter later...my car seems to be back up to par.
Have you checked the fuel pressure?
Last time the fuel filter was changed?
Considered that the curb might have dislodged something with the fuel system/pump?
Admittedly I haven't read the entire thread. My thoughts would be to put it up in the air and look over the tank, fuel lines and anything in the path.

my friends brother checked the fuel pressure and said its fine until it hits closed loop mode then it leans out until the car is fully warmed up. I dont think it knocked anything loose i think it may have knocked a fuel pump ground loose if there is one. If not i have no idea and im going to go do the intake manifold this weekend.

If you are running lean like that...I honestly doubt you have an intake problem. i've been wrong before.....
Once the car warms up you have an issue, is that right? Maybe the fuel pump is also warming up?
On that pressure test. Was that sitting still or driving? My tests said the pump was fine...however...my pump was failing. The fuel pressure test isn't 100% at all...it leaves plenty of room for error.
Do you know what pressure the car was idling at?

still working on getting the fuel pressure checked. today i was driving and the car did 60 up hill without me hitting the gas and when i got to the stop sign at the end i hit the brake n left it in gear and it dropped down and was fine the rest of the day but when it was doing 60 i put it in neutural real quick and the rpms were really high so i dropped it back in drive real quick. i really have no clue whats wrong with this thing
