2000 Nissan Maxima

My car has 110k miles now and I thought, and the carrecently started sputtering and just not accelerate. Mechanics and owners both told me to change the ignition coils and I did. When that didn’t work I brought it to Speedie and after a diagnostic test they change the mass air flow & fuel pump. It ran better but now when I turn while depressing the gas the car seems to lose all acceleration. Please tell me if this is a new problem?

Did you have a check engine light? If so, did you get the code read? If so, what was it?

The check engine light has not come on since the work was done.
