Do you have access to a scan tool that has live data? If so, check the short term fuel trims. Do this with engine running. Spray carb cleaner around your intake, etc and see if the voltages change on the fuel trims. Also, drive this with the scanner hooked up, and check your calculated load reading. When you have the gas pedal floored, such as pulling a hill, or passing a car, your calculated load should read above 90% of not, replace the MAF.
