Depends on the yr/make/model.
My '66 shutters alot when it's cold too, but it's normal for my car because today's gas is different than the leaded stuff in the '60s.
The first thing you need to do is figure out whether it's due to too much gas or not enough.
If you have a carbureted engine, put your hand over the mouth of the air cleaner's intake tube when it's shuttering. This will cause more gasoline to enter the air stream. If the engine runs better, you're experiencing a lean condition. Check the choke to be sure it's closing and opening freely. If the engine runs worse when you put your hand over the intake, you have an over-rich condition and you need to find the appropriate adjustment and tweak the thing a bit to get more air and less gas.
It could be nothing more than some fouled out plugs that are angry with you for making them work into their old age. Retire those old dogs with some sparky little brats and you may see your problem go away.
If your car is injected, the engineers always figure out a way to get more gas to the engine when it's cold. Whatever that thing is is what's probably screwing up. It could be a sensor, or some wingy dingy somewhere that isn't working. If you can squirt a little gasoline into the intake when it's shuttering, you can determine the problem, but because it's hard to see what's happening electrically, it's difficult to diagnose without the kind of experience and/or technical training to pinpoint to problem.
Now you know why most people drive cars less than 10 years old.

Do not rev the engine when you start the car. Shutters in the cold are not uncommon, but just do what you need to do to get it going. Then, let it warm up a bit. If the shuttering happens in warm weather, that may be more serious, like a value problem.

You may have a bad choke pull off if it has a carburetor. Bad plugs / wires or moisture inside the distributor cap.

Do you let it warm up? It takes time for oil to heat and lubricate the engine ..frozen oil is jellylike ..think about it

this is probably a dirty fuel filter.
