This has been going on for months with many hundreds of gallons of gas from several different stations. Arizona does not have 85 octane available anyway, so if that happened the delivery truck would be WAY of course

engine coolant temperature sensor could have an issue it's staying at the correct temp ?? right? 99C
have you done any mods or changed anything from stock under the hood?, a knock sensor detects knock wherever the source may be...
I have seen bad maf sensors cause a whole slew of other issue's also, just something to possibly consider
could be a bad (new) knock sensor also like James mentioned

Bone stock. No mods of any kind anywhere, not even cosmetic.
If it was the temp sensor or MAF, would i see a fault code?
It is holding temp just fine BTW

***CAUTION*** I do my own stunts!
I didn't realize the torque on these was that crucial... when I swapped mine i just tightened them up to what i thought would be good... not overly tight but good and snug so they wouldn't rattle around... no issues with mine after install so i must have guessed correctly... lol
a bad or failing maf wouldn't necessarily throw a code in the beginning it would eventually, I have seen them cause misfires, rough idle, loss of power, transmission shift problems, cause 02 codes, cause throttle body codes, surging, just all kinds of problems, a bad knock sensor would MOST likely just throw code and maybe cause some pinging, I think it would be unlikely to cause much if any loss of power like you are describing (maybe it could) but I have never seen it happen, seen plenty driven around for quite a while with no noticeable problems other than a check engine light. I'm not saying run out and buy one, but maybe get a can of MAF cleaner and clean it and the throttle body and swap those knock sensors and see if the problem follows the knock sensor and/or if the power issue re-occurs.
