cutting out when accelerating

Hi. I have a 97 lesabre with 156k. The car doesn't want to go at first and then eventually takes and goes fine after it is warmed up a little I have replaced the following parts.
fuel filter
spark plugs and wires
o2 sensors, before and after the catalyst but still getting trouble codes for them.
had Sears run a detergent through the fuel system

Sears told me the Mass air flow sensor was bad because when you take the air duct off the throttle body you can see that the screen has been damaged by a dent and gash and they told me to replace the maf. It looks to me that the sensor is fine, it is the screen that is bad. do i need a whole new throttle body?

Would replacing the maf help my car run any better when accelerating?
Thanks so much for any help you can give.

No check engine lite? The screen on the TB would have to smashed to affect performance.

What are the numbers you're getting for the trouble codes for the O2s?

What sparkplugs did you put in? AC Delco is the way to go with the 3800.
