Steve,
I'm not sure if they reset the codes, but the car runs just fine. The gas that was in the car from the dealer is now completely gone after I filled up this morning.
I have already added some fuel injection cleaner to the current tank to hopefully clear the fuel injectors out.
I'm almost wondering if the dealer was being 'cheap' or 'ignorant' and might have added 87 octane by mistake.
