92 Lt-1

Having a problem with car at idle and when you try to accelerate. At idle car is missing pretty bad (if you step on gas a little to raise idle it goes away). Then when you try to take off from a stop it runs pretty bad. Have replaced the cats,02 sensors and map sensor,egr valve and fuel pump and fuel filter even spark plugs (was giving me code 32 replaced egr valve code is gone,no codes now) Any ideas would be great??
Car is a 92 LT-1 automatic

If it seems to run good when cold (open loop) try replacing the coolant temp sensor.
