Starting issues in the cold!!!

[willhholla1]

When it was warm my car started fine.

Now that it is getting cold my car will start and immediately cut off if you dont hold the gas for 2-5 minutes until it warms up depending on how cold it is.

Any info would be greatly appreciated, thanx!!!

Sounds like a tightened IACV

Don't really remember on the F22's, but I know on my 4G63 the coolant temperature sensor causes this....when they go out, they read a really low resistance (high temperature) and the engine doesn't squirt enough fuel for the cold start. Could also be the FIAV/IACV. Could be a vacuum leak. Check for vac leaks then move to the throttlebody and associated components.

People, people! Keep it simple, will ya? Test the cold cranking amperage of the battery. When's the last time you replaced it?

....the car starts, runs and shuts off
Battery is no issue

[cb9wagon]

was the FITV swapped too?

[willhholla1]

yea it was swapped 2, i jus found out i didnt hav a thermostat so i just put 1 of those in and now my heat works and it takes a little less time 2 warm up

[willhholla1]

how would i no if my IACV is tight or not...i had a shop adjust it when i was having idle issues,,, im considering changing the coolant temperature sensor and seeing if tht works

If the engine shuts off immediately after starting, it could be a cold cranking amperage issue.

No.

explain the reasoning behind your theory?

I'm thinking he means battery cold cranking amps. CCA is used to define the ability of the battery to crank the motor over in extreme cold weather.The rating is the number of amps a new, fully charged battery can deliver at 0* Farenheit for 30 seconds, while maintaining a voltage of at least 7.2 volts, for a 12 volt battery. So in that case the battery would be weak in some cases if the car takes a long time to start. What this has to do with the engine AFTER its running IDK.

I wonder if the ignter is acting up. Any check engine light?

How's the all basic stuff? Spark plugs and cap/rotor specifically.
Coolant temp sensor isn't hard to replace and not much money. But a preliminary check of all the basics would be a good idea before throwing money at it.

No.

Yes.

If the engine shuts off immediately after it turns over, it could be a cold cranking amperage issue with the battery. The alternator then must be run for some period of time (the time depending on the condition of the alternator) to charge the battery enough that the engine can run on alternator power. And yes, the battery needs to have some charge in it in order to continue engine operation if it is still connected to the alternator. Since the OP has been having problems in cold weather and the engine is shutting off IMMEDIATELY after starting, a cold cranking amperage issue is feasible. Just because the engine starts does not mean there is no problem with the battery.
