I warm up the car and then taking off the car acts like its going to shut off (it practically stalls) then drives off normal. Does it through out the day sometimes. Its been doing that for over a year. Im clueless

Lack of acceleration, chugging, hesitating********, bogging, misfiring etc. Could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

It could be due to excessive low idling, bad spark plugs or related components and valve clearances out of specs. Have those checked as well.
