Rough idle

2011 Chevy camaro5 2ss. 69k miles no mods

So I have seen posts about it lately but not a clear fix of it. My camaro has a moderate rough idle when just sitting or getting off a freeway is the worse. You can watch the rpm gouge flex between 500 to 800 rpms. The performance of the car is not effected. I have read forms that the camaro idles at low rpm and just to get used to it. But it gets annoying after awhile.

Any thoughts? I am a good mechanic but this is my first gm product from being a big ford time person

try cleaning your MAF sensor.

From the factory they idle around 500-550. Like Chris said, try cleaning the MAF first and see if that helps.

So I cleaned the MAF sensor and it was perfect and I also checked to see if it was the weak one and it wasnt.

So spark plugs?

Also check the stock plug wires, one of the first things I did when I got my 2010 used was a plug and wire replacement, when I pulled the 7 or 8, can't remember, it just fell apart and you are in their anyway....

Did you clean it with MAF cleaner? You really need to use a specialized cleaner like CRC MAF cleaner. I just did it and I had the same problem as you and it went a way.
