Engine Performance problem
1999 Chevy Tahoe V8 Four Wheel Drive Automatic 190000 miles

MY TAHOE STARTS FINE, WHEN I TRY TO GIVE IT GAS IT BOGGS DOWN, WHEN I USE THE GAS PEDAL LIGHTLY IS RUN FINE, TAKING OFF IT IS VERY SLUGGISH. I HAVE REPLACE WIRES, SPARK PLUGS, AIR FILTER, FUEL FILTER AND HAVE REPLACED THE FUEL PUMP ABOUT 2 YEARS AGO. COULD THE O2 SENSOR BE THE PROBLEM

Ok if you would unplug the mass air flow meter and then see how it idles and performs (keep in mind the engine light will come on). Now if it runs better then clean the mass air flow sensor with mass air flow cleaner (nothing else). Get back to me on how it goes.
