mass airflow sensor throwing codes

[Nateco]

i have a 2019 chevy silverado 1500 ld 4x4 so its the 14-18 body style basically same as the lt.. i put a K&N cold air intake on day after i bought it ran great for 20k miles with it then sensor went off check engine light on  figured maybe i didnt let it dry enough and some of the oil from cleaning it and respraying it got in noticed a heat spot on the sensor so bought a new one installed it waited about 100 miles still seeing the code tho...  took the truck to chevy for other problems my wipers stopped working apparently the fuse box blew so they replaced that and the wipers work now, it was having issues starting they said needs a battery but tripple came out said my battery was fine turns out my starter was shooting sparks so needs a new starter but when it would start at the dealer it wouldnt run and would throw the sensor for mass air flow which it has always run perfectly fine with that sensor on regardless so little confused whats going on
