If your SS idles rougher than you think it should.......weak MAF and un-modded engine
Ours used to idle rougher than I thought it should until today. It is completely bone stock. Read the post about the weak MAF sensors and checked ours and sure enough it had only a "P" marking.
Got the AC Delco 213-4222 for $40 from an un-named source. I knew I would not get a weak one. Sure enough the roughness at idle is gone. Tomorrow when it's cold we will see if the mild hesitation is gone. So it appears that even though the engine is NOT modded, the weak MAF sensors still have an effect on it. Just FYI

They do make a difference especially after modifications. My car had some surging during partial throttle with light loads on the freeway. The strong MAF fixed the problem instantly.

After a few requests, if others have not figured out where to get these, I will put up a link.
You should be able to find these on your own though.

Don't replace it if you have the correct mfr code

Thanks
 I think I will be ordering this shortly, I feel like I've probably got a weak MAF, but have yet to pull it out. Symptoms are exactly as you describe. Guess I know what I'll be checking out tonight when I get home!

Yes mine is the single letter one but other than a rough idle at start up I don't have any other problems. Was going to replace it but all parts stores here want $70 and there are no codes in the "window" so cant tell what I'm getting so I haven't bought one yet

I didn't really have any other symptoms but this really did smooth out the idle.
Had already done the fuse pull and we've been using 93 octane for 5 months now and that never helped the idle but this did the trick. Best $40 I ever spent.
