What I'd like to know is whether or not misfires are logged in the ECU despite not triggering a CEL or storing a code. I'd think this could at least point us in the right direction or maybe narrow down a particular cylinder.
Has anyone ever tried running Techron or some other fuel injector cleaner just to see if it makes a difference?

i tried the Techron cleaner 12oz bottle on a full tank, it didnt really make a difference.
I replaced my plugs with OEM ones from the dealer, i just dont understand why plugs would trigger this, i replaced them at 54k miles.
