Rough Idling on a LS? HELP
K,
So I've noticed as the cold weather came into season, that when I start my car the rpm drops very low (shut off sometimes). Other than that if it doesnt shut off, it Idles rough back and forth for about a minute and becomes calm. Anyone else have this problem?

There's plenty of cobalts with an intermittent rough idle problem. There's a tsb for it. Dunno about it going on for as long as a minute. Couple seconds max is regular.
If you have an aftermarket intake it could possibly cause the problem to be worse, or your tb could be dirty, or you could have oil/sludge build-up in your intake manifold. Just some things to check.
