Does your car actually have problems ? P0302 is misfire in cylinder 2 , with a LOT of potential issues ( sparkplugs, injectors…). But if your car doesn’t currently seems to be having engine problems , it is possible that these are older codes for problems that happened once in the past. for example… could have had some dirty bottom of the tank gas and created one random misfire. Often one problem links to others and generate other codes. if your car doesn’t have problems . I would suggest your clear The codes, and run the engine like that. Check your codes frequently, and not the first one showing up. If they happen more or less at the same time And quickly after the engine runs , you likely have an Issue, but come back here and let us know, with more infos and symptoms. good luck
When you look into your settings you may have the case where you see 2 kind of similar names for your input device. They are not exactely the same . (I had the case with a Bose) , one is for stereo audio, and one for mono. when i selected stereo, microphone would not work. so try to look for this. You have to select MONO .. ( yes , somewhat related to the rings on the audio jack..)
