accleration problem

he, i have a 99 s-10 blazer and need help trying to locate the
problem, the truck will start and idel just fine but when i try to
acclerate it want to bog down it wont kill or stall but it has no
power and doesnt move. i had one guy tell me it could be mass air flow
sensor or fuel injector sensors. i have had good luck on here befor so
i wanted to see what people say thank you.

Try replacing the fuel filter....start with the simpler and cheap
explanations first. Adequate fuel for idle but not enough for acceleration
is a common symptom of this. If it still does it after a filter replacement,
it's time for a shop to diagnose it. Remove and replace the MAF sensors or
others is expensive and not guaranteed to give you a solution.

The fuel pump, filter, and relay are new (replaced in last 6 months).
I have also replaced spark plugs and plug wires.

clogged cat

My first guess too.

It would be nice if you included trivialities like this in the OP......

Start the engine. Put your hand behind the exhaust. Is there air flow?
It may be a clogged catalytic converter.
