Engine stalling after replacing mass air flow sensor

Replacing a mass air flow sensor can sometimes leave a vehicle shaking, idling weakly, or stalling at red lights. Even with a new OEM sensor or after reverting to the old part, secondary trouble codes like a P0106 MAP sensor issue can persist, preventing the engine from running smoothly.

“I have a 2019 rogue and the check engine light came on. The code was for the MAF sensor P0101 and I replaced that. However even with the new oem maf sensor my car stalls at red lights .”source ↗

“Okay fine so I get it scanned again and now it has the MAP sensor code P0106. I found it odd that both sensors would go bad within a week of each other”source ↗
