2014 Infiniti q50 3.7, battery light appeared and reverse camera stopped working after I checked each fuse from the fuse box next to the battery. I was thinking that a fuse blew or was left loose so I went back to check and everything was fine but I still changed every related fuse to a new fuse. Even with all that, it still didn’t fix the issue. Both battery and Alternator were changed like 1-2 years ago. Could I have pushed down a fuse terminal deep down or something? Or something else

Car has been having air fuel ratio codes for both banks and misfires from cylinder 2 and multiple misfires. Been trying everything to replacing fuel injectors, to spark plugs, to ignition coils, to maf sensors and to throttle bodies. I checked for vacuum leak using smoke machine but nothing has changed the problem. Live data shows car running rich with not a lot of air but maf sensor data shows bank 1 getting almost no air while bank 2 getting impossible amount of air. Is this some electrical failure? Or I’m missing something else?

Ever since I got the Tesla screen, the codes appeared and supposedly has been messing with my cars ECU (not confirmed). People with the screen, have yall gotten the same issues and if so, what did yall do to fix it?

2014 q50 3.7. From the beginning of time, this car has always had an issue. Lately the car has been sluggish like not as fast as it should be. When I got it back from replacing the fuel injectors, it ran like crazy and was the funnest time I’ve had with it but it’s been slowly going downhill since then. I’ve checked live data to see what’s going on and noticed that the maf sensor from bank 1 is reading no air coming in. I did a vacuum leak test and could not find a single leak point. I tried testing voltage of connectors, everything is fine. I tried relearning my throttle body, same result. Spark plugs changed, ignition coils changed, new maf sensors changed and nothing at all. One thing I know is that the relative throttle position is way off and close to 0 to none. I bought a new throttle body to replace it but I’m unsure if that’s cause either way. My next stop is checking all fuses to see if ones blown or bad. I’m not a mechanic so all of this is stressful but is there something that’s I’m missing to check?
