Onwants to stall when first starting when cold out

You don't say what make of car but it's about the same for all. Your problem is the choke adjustment. The choke raises the idle when the car is cold and after warm up drops to normal. You are doing the chokes job when you hold the pedal down, once its warmed up the choke no longer functions till cold again. So check the choke and the high idle speed adjustment. Simple fix. Hope this helps mike

clean the iac sensor

Oxigen sensor. Check accelerator pot also, and fuel pump.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Do the following service it should help the stall out.

Engine stalling and rough run issue at low speeds

Sounds like your throttle body and throttle plate are full of carbon.You also have a idle air control motor with a pintle on the end that gets carbon on them.Go to your local parts store and get a can of throttle body cleaner and a old tooth brush and clean throttle body and plate and if you can remove the IAC and clean the pintle and bore. that should take care of your stalling.

Most common cause of stalling for Lincolns in that era is the TPS (Throttle Position Sensor). It regulates fuel mixture, idle speed etc. A bad TPS will usually act up in one of two ways:

1. When cold, car continually stalls
2. When warm, car stalls when slowing down (especially if AC is on)

As far as valve cover oil leak, it's a problem that should be addressed to keep oil from fouling your spark plugs but highly unlikely to be the cause of your stalling problem. Hope this answers your question. All the best.

You have a cold start injector. It basically primes the fuel into the engine.
It`s like the old type `choke` systems.
Get it checked at an auto electricians.

Sounds like a bad IAC (idle air control valve/sensor) that controls your idle when going from throttle to idle. If bad your idle will act crazy and can cause stalls easily. Pretty sure that's it.

it sounds to me that you idle controll valve isnt responding (could be dirty) get a can of carb cleaner and clean the thottle body inside and with the engine running. squirt just a little and the engine will start to stall and the idle air controll will start to open ( you will hear it start sucking) then spray more in sperts try to keep the engine running at idle . this will make the engine RPM's change and open and close the idle controll valve thus cleaning it. when done save some carb spray. put the air cleaner hose back on. and start the engine and with the engine idling spray around the intake and base of throttle body if the rpms change you have a vaccume leak than will need to be repaired.
good luck
