no hoses are off.
everything is p;ugged in..
its weird.. when i first started it it did the cold start.. and everything worked out fine... went for a cruise... and then turned it off and has some lunch. once i went back outside to turn her on and go out, it just dropped right off, with a little bit of stumbling.

i tried to ground the damn thing to stop my 3800 rpm hesitation.. helped, but now i cant start my car easily, or stop at a stopsign or whatever.. just stall out.. i have no idea what do do... i have joined the original wires together, without any aditional grounds, just the way it was before i fucked with it... stil wont work.. but, i havn't disconnected the battery since my last attempt of rejoining the wires together.. would that somehow make it work, since it would be resetting the computer?
any input is greatly appreciated, as i kinda need to get to school tomorow am
lol

damn.
tried it, didn't change.
when it starts up and it is cold, it is fine,
but when i turn it on and its warm, it just drops right off..
could it possibly be the ground i added isn't grounding well enough?
this is really annoying, and it cannot be too good to keep turning her on everytime is stalls (whenever i try to start when warm.. usually takes me 3 tries to get her, with a little nursing

please.. anyone please help.
i just reconnected and soldered the original boost sensor grounds back together. --- the best solder joint i have ever done. but it still does it..
this is exactly what happens..
i will turn it on (when warm) and it will go up to 2500 rpm, then slowly drop to 1000 rpm, then it will just drop right off, it will then jump back to 800, then down to almost nothing (all the light will come on in the car.)
this makes no sence, and it sucks. i dont know what to do next, because i have put everything back to the way it was.
i am sure all wires are connected, and i am sure everything is plugged in on the pressure/boost sensor
this is driving me crazy, its making me feel like i should just throw this ****** car away
please.. please help
P.S. the ECU is throwing no codes.

It sounds like you have a HUGE vacuum leak somewhere. Re-check the connection from the AFM to the throttle body. You might have knocked it loose but not enough for your car to not start but came loose after driving it.

nope.. checked that
it was fine before i cut the god damn ground from the pressure sensor to solder on another ground..
all i did was chopped it, and solderd on another wire.. i did't play around with anything else at all.

basically the same thing, aint it?

Here's a quick&dirty test to see if you did screw up the ground mod...
Unplug the pressure sensor via the electrical plug and go drive around.
Does this change the way the car drives?
If it does, then you screwed something up.
If it doesn't change anything, then it's something else...

ofcourse unplugging the sensor will change the way my car drives.. wont it?
i dont see how that method would tell me anything
this ONLY happens when it is warm.
when its cold it starts fine.
