need help

I have a 94 mighty max i'v been driving with mass air flow sensor bad and i just replaced with a brand new one and now in 5th gear at around 60 mph it starts bogging and i have to hit the gas kinda hard really quick and it clears up .... does any one know whats it could be i changed spark plugs and wires, cap and rotor and there is no check engine

Did you disconnect the battery for a few minutes to clear the codes out of the computer so it resets and will read the mas correctly?
