Maf Problem

[2000gmc]

Check Engine Light Keeps Coming On P0102, I Replace Sensor And Connection On Maf, Cant Figure Out Why It Keeps Giving Me The Same Problem. Recently Addition Before The Light Came On Was A In Line Fuel Pump, And Tires. The Fuel Pump Might Be Making My Truck Run A Bit Rich. Plus It Slugging At High Rpm. The Truck Has Not Been Re Tuned Since I Add It The Fuel Pump. Will Greatly Appreciate Any Helpful Hints. Thanks

First thing I would say to do is get some MAF spray cleaner and clean it really good.

Recently oil your air filter, like a K&N or something?
