Got the MAF error code( bank1, bank2 both lean). The problem is that I've already changed MAF sensor, air filter, cleaned the air box and cleaned all 4 O2 sensors. Still getting the code! Recommendations please

Same, me too. Replaced MAF Sensor. Getting that code and have replaced as well. Also getting o2 sensors. I cut 2 cats off leaving cut off behind bottom sensors a few inches out past Bottom sensors, leaving 2 cats on the upper towards manifold and 4 sensors. Loud as hell and acting as if I’m limp mode. Any suggestions??? Before I purchase bypass? Check wiring and what not, deleted codes they come back. Thank you !
