2005 Pontiac G6, V6 138k
Just picked this up for $450, no engine codes. Runs smooth. Interior could use a cleaning and replacing tie rods later today.
But at idle, it runs smooth but almost feels like a misfire often but not quite and there isn’t any codes.
Anyone have experience with this?

by the time the CEL flashes at you, the problem is so bad that you need to stop driving. No light doesn't mean there's no misfire at all. With a good scanner, you should be able to get a live misfire count for each cylinder.
