    When cold, it almost always runs a little rough, almost like its on the edge of "missing". Don't get me wrong, it sounds mean (like my race cam in my c6 z06). The idle does smooth out after 30-60 seconds. I've been told that's how they were "released" to the public. I have seen an improvement since the engine was new. It's better, but it's still there during certain conditions.

    I have all the latest PCM updates except the one that was just released a little while ago (like a week ago, which seems to be related to other issues I don't have).

    Anybody know anything about a "rough idle" fix coming? I was surprised I didn't see more posts about it...

    Mines okay, did yours have a fuel rail recall?

    My car almost dies when cold starting, idles really rough for 3 sec but that's only when the car has sat for a few days and not driven.

    Cold starts day after day are fine on my car. No problems.

    Needs to be a fix because it's embarrassing to have a 70K miss in front of other people and family.

    My HC idles rough for the first 5 to 10 seconds on a cold start, always has. Dealer has updated everything and it runs like a top after the first few seconds. I figure it's just "shaking it's head" getting it's eyes open.

    Mine occasionally has a rough idle. It acts like it's got a monster cam in it. Never stalled, no codes, generally smooths out. I actually like it. Sounds mean as hell when it happens. I do find it odd since it is a computer controlled vehicle but at the same time I like it ;)
