5.0 is stalling!!! help

well guys i go ta 5.0 t bird with an aod

I live in Ny so in the mornings its cold now and when i start up the car after about 30 seconds it stalls or when im gonna move it it stalls. I changed the tps sensor, the idle air control motor, and the 5.0 has been through a tune up. Can someone help me out on what this could be. I think it could be the alternator cause its pretty old and for reference the fuel pump was for a 3.8 engine that was previously there.  Someone help!!! plz

Are you pulling any codes? I had the same problem and it ended up being the EGR Valve Position sensor.  I've had to change that piece twice already on this car.  Both times it happened I was pulling code 33 from the computer.

1) Look for a vacuum leak, those old plastic vacuum lines are brittle.
2) The EGR selenoid can been cleaned so it moves easy.
    It carbones up a bit.
3) Rich cold idle selenoid can be cleaned and one drop of oil so it  moves easy. Its right beside the TPS.
4) Increase the idle mechanical stop screw which stops your gas wire on intake butterfly (underside where TPS is). 1/4 turn on mine fixed the problem.

There are only two tools you will ever need:
1) WD40
2) Duct Tape
If it doesn't move and should, use the WD40.
If it moves and shouldn't, use the duct tape.
