Does this make sense?
My 2001 F-150 4.6L was hestitating around 1500 RPM and the check engine light was on, dealer said the oxygen sensors needed to be cleaned. Had the work done and the problem still exisits, the check engine light intermittently came on. I tried 89 octane fuel and the check engine light is off and the engine runs smoothly. I'm just a weekend mechanic and can do mostly basic stuff but the only time I've come across something like this is when I accidentally put 87 octane in my bike. Does this make sense?

You can't make sense of it because the CEL and code/s should have been known first, as a reference.
Ox sensors are never 'cleaned' by a dealer. They won't normally fool around with such actions, for the 'unrelability' of it.
They replace them. You really don't know what they did.
.
Fuel octane:
Besides what's in the formulation, higher Octane slows the rate of combustion in the cylinder.
How this all ties togather in your situation is anybodies guess.
.
I would even say that if your lucky the CEL and code will come back so you/we can get a basis of what the computer sees as the problem.
Then address the problem.
Until then it's only guessing.
I hope you can see the common sense put forth.
Good luck.
