Well you got half the tune up done, So replace the fuel filter and air filter. Gets some brake cleaner and clean inside the throttle body. check all the vacuum lines and make sure they are not broke or leaking. Also check the catalitic converter/s, These start clogging and will excessive fuel consumption.

I respectfully disagree.
A P-0300 will NOT be set in a Corolla by a dirty fuel filter.
Replacing the fuel filter could be a very costly operation, as I have observed that the fuel line threads that connect to the fuel filter easuily get damaged when removing the fuel filter.
In short, don't replace the filter until you are SURE that it is the culpit.
In this case, the fuel filter is NOT the culprit..
Save your money; and your time.
Additionally, premium fuel does not clean fuel injectors. That expense would be a waste of money. The engine will actually run WORSE on premium fuel; the engine is NOT designed to run on premium. 87 or 89 (better choice/89) is the grade to use.
If you really want to track down the P-0300 code, which is a multiple/random cylinder misfire, I would look at the quality of the fuel in the car; ie water in the gas. Second, I would remove the plugs and examine them closely. A worn center electrode will also set the P-0300 code, as will bad/weak plug wires (over 5 years old).
Please feel free to contact me back if you need further assistance. Thanks for choosing FixYa for assistance.

Start with the plug wires.You may need new plugs but my experiance is that the plug wires are the first to go.

Disconnect the wiring plugs from the injectors, Then remove the fuel rail (which is attached to injectors). Then remove injectors from the fuel rail. Don`t forget to change the "O-rings", (little rubber things on the end of each injectors). Otherwise there`s a possibility of fuel leak.
Also I suggest trying to clean the faulty injector at first, It might be ok, just dirty inside.
How to clean: Use injector cleaning fluid on the end of the head of the injector. Attach minus and plus to the contacts of the injector to battery of the car or any other energy source, and start pulling the negative wire on the battery on and off. You should hear clicking sound in the injector. Use the fluid and this "technique" for couple minutes or more, until the injector starts spitting the cleaning fluid evenly, not rarely.
If still the injector doesn`t spit the fluid, you might need to change it.
Hope this helps, sorry for my english. I`m a lithuanian

check/test cam and crank sensors. If defective, this will cause a misfire on the spark or the fuel side. If ok, check all electrical wiring for corrosion or if rodents bit any of them.
