Have a 2011 Acadia, misfires when cold but not when warm. Have replaced plugs and coils within past year. Just started doing it now that its colder. Engine light comes on and throws codes of multiple cylinder misfires. Has almost 200k on it. Cant use remote start because it will shut off.

Anyone have any ideas about this?

A number of things come to mind. Can't begin to speculate without a list of the codes. BTW, remote start will not work until the trouble codes are cleared and the problem is resolved.
