2012 Nissan rogue S AWD 90k miles.
codes: P0303 and P0101.
i changed the MAF sensor, filter and cleaned the intake but the code keeps on coming up.
same thing with the other one I changed all the spark plugs and coils (expensive stuff btw) and code keeps on coming back.
Definitely something else is wrong as when I’m on a stop or car is idling it would shake and rpms would go up to 2 and back to almost 0 and it feels like is gonna shut down.
also there is a weird electric sound like peeeeeeee in the rear right of the car by the wheel idk what it is.
Long questions but thanks if you read all that.
anyways like you know classic Nissan is dying on me.
Did you replace the MAF with an OEM sensor? Try to avoid the 'replacing parts first' method of diagnostics, it's seldom fruitful. Try checking your engine's live data, these values can give further insight. I've had a poor idle on my Tacoma be completely resolved by stopping a vacuum leak.
