It certainly could. Might as well get a fuel pressure gauge and find out. Hopefully its something in your fuel, because those were my symptoms when my opti went. Backfiring at first, then sputtering, then knocking. At higher rpms it didn't knock, but there was significant power loss. But you might as well check the fuel first since that's what's easier and could be throwing the code. But either way don't feel bad, both my ignition and my fuel system have been giving me crap since I bought my car.

When my rod was knocking i had a very similar problem with mine the knock sensor was backing the timing off so much it would cause it to run like **** and i had no power. Hopefully this isnt the case for you its more than likely clogged fuel filter, bad fuel pump, or maybe it could be some bad injectors im not sure on that one i have never had an injector problem (knock on wood) but ive had every other problem
