I have a 98 Toyota corolla, and recently it's been acting up on me. When I am at a complete stop and then accelerate it hesitates, or acts like it is choking. Once it gets going it's fine. If I have a/c or vent air blowing, it really Boggs down and acts like it's not getting fuel or choking. But again once it gets over that initial hump, from stopped to first gear it seems ok and I have no problem with power.
Does this year corolla really not have a fuel filter that can be serviced? Thats what I thought it most seemed like to me but I'm just a beginner.

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.

Note:If it doesn't apply disregard it and keep testing.
