When you checked the MAF what did you do?

Customer reply replied 6 months ago
Drove the car for miles with sensor disconnected to see if it affected performance. There was no change in performance.
Chevy Mechanic: Mechanic01, ASE Certified Technician replied 6 months ago

Ok I would pull it clean it with MAF spray and reconnect also monitor it on the scanner while messing with the connectors to see if there is any change, the wiring on that has issues sometimes
