Check engine light flashes at highway speeds. Have run out of ideas. Help please.

Have you tried running a different brand of fuel or jumping up to high octane for a few tanks to see if it impacts the misfire?
Basically, what I am thinking of here is the possibility that there is some carbon deposits in those cylinders that are causing pre-ignition.

I have used Arco and Circle K.
I also use Premium.
The thing is though, when I hooked up the scanner, 3 misfired a bit more than cylinder 6 at idle, but once I revved it up, they misfired nearly identical. Would carbon build up cause misfires at nearly identical rates at higher RPM's and highway speed?

Oh yeah, I used regular at first, then when I did the tune up and I changed out the injectors, I switched to premium.
If I can get access to the bore scope and there is excessive carbon build up, how would I go about fixing that problem? I am open to any suggestions short of buying a new engine or tearing apart this one, though I don't think there are many options left with all that I have done.
