Stalling issue, throttle hesitation and throttle plate sticks

Okay, I have cleaned the throttle body, cleaned the MAF, changed the air filter, changed the spark plugs (still waiting on wires), changed TPS, and changed ignition coil. This car still has trouble stalling. I must be getting somewhere because it's better but at the moment i've had to turn the idle up quite high to keep it from stalling when the lights are on. There is also still hesitation from the throttle and the throttle plate sticks when the car sits for awhile. Any help would be great.
