I have a 2011 V6 RS Camaro that runs good but every once in a while, it starts to miss and run, rough smoking and reduced engine power message comes on I can disconnect the battery for a while reconnected in the car does fine for a little while then it does it again. This has happened for five times any help is greatly appreciate First time Camaro owner

 

You need to pull codes. It can be so many things. Even with the codes you need to figure out if the code is a result of the issue or the cause. In that year range I am used to the low power message having something to do with the drive by wire system but I would want to see all the codes before doing anything.
