Car always starts up fine, and if it's WARM outside, I can hardly tell there is a problem.

BUT... When it's COLD outside, it will start right up, but begins to cut out and miss - spits & sputters. The colder the temp, the worse this is.

Then, when engine reaches operating temp, it runs fine, and will continue to run fine all day. It acts like an ignitor problem break down. I have replaced plugs & wires and distributor cap & rotor. Have even added manual choke cable, but nothing helps during cold weather.

Would appreciate any help/suggestions. Thx.

 

is the cold air valve working on the intake?
