As another minnesotan winter is just beginning, I am not familiar with cold-weather 'glitches/issues' with carb'ed autos, especially dating back to 76.

When my ltd is cold, and I start it up- it idles like crap, with a real bad lope; when I start driving (and it's still reasonably cold) it will sometimes (this is kinda hard to explain) putter out, so to speak. The engine will kinda die down and then pick back up after my putting the pedal down in reaction to keep it alive.

The carb is due for a rebuild, which I'm planning to get done this weekend.

Other than that does anyone have any say in 'normal' cold issues as well as anything handy you'd like to say ?
tx in advance.

(Cold as in the temps are freezing or lower)

I gather you don't have a choke? Otherwise it's normal for an engine without one. I've experienced it and also seen it on other cars not equiped with a choke.

Obviously it's not set correctly. With the choke on it shouldn't idle less than 1000rpm.

Hello thinice.
I think your winters will be colder and more of a challenge on warming up a car quickly than we experience down here. However, Brendan is right. Your choke is stuffed. Your 1976 Landau-nice car by the way-was designed to cold start initially with a fast idle of approx. 1200-1600 rpm. And you should be able to drive the car cold without it stalling. Your carby rebuilder should be able to fix this problem. What type of carby do you have on the 400?
Cheers

Hello thinice.
The stock standard carby for the 400 I believe. For the price of a rebuild could you get a two barrel Holley, or do emission controls make this difficult? Not sure how strict your authorities are on policing this aspect. Even better would be a four barrel inlet manifold and 600 Holley! There you go thinice, I've worked out how to spend your money for you!
Cheers

a buddy and me are rebuilding it; so in total it's costed $24 (cleaner and kit) (so far )

I'm planning on a 4bbl holley conversion hopefully around jan.
Emissions? In this town? That's a joke.
