firebird20

I have a 95 lt1 firebird it recently started acting up it runs a pit week the engine sputters at low rpms, once i accelerate over 2500rpms i dont feel it shaking anymore. Need help to find out whats wrong i already changed spark plugs, wires arent old checked them all they all look good. Vacum lines arent leaking accelerates with rhythm of car so fuel filter is good dont know what it could be.
