I have the check engine and vsc light on, and code P0300 (get the code from autozone)

this is first happened after oil change about 200 mile.
I read forum and learn it could be the hose behind air filter was disconnected, However I cannot find the hose, so I just ignore it for two month drive with this code on, now I have time thinking about fix it, with this code, if it could still be just the hose? where I can find the hose?
thanks

That code should have nothing to do with the hose behind the air box. That code points to a random misfire. If the car is running fine it is probably nothing. Clear it and see if it comes back.

The check engine and vsc came and went off two times in the past two month, each time stay few days, then the third time came on and stay until now.

if this is not the hose, then what I should to do with it? thank you very much

Is the P0300 the only code? Usually it's accompanied by P0300X, the X being which cylinder is misfiring.

yes, this is the only code, if it is the misfiring, how to fix it?
