P0300 Code with high Idle

40thzzz

So my engine light turned off. I replaced my spark plugs and coils, cleaned throttle bodies, and cleaned my maf sensors. I cleared the code after replacing the spark plugs and coils and it came back, i also cleared the code after cleaning my throttle bodies and it came back, but i didn’t have time to clear the code after I cleaned my maf sensors but after driving for a few days the engine light turned off today. I’m not sure if the code just turned off randomly or if any of this helped but I will update if the same code comes back on.
