Does it clear once the car is up to temperature?
Normally bogging down when cold is due to the car running too lean for the lower temperatures, which is either the coolant temperature sensor (you guessed correctly), or possibly the throttle position sensor (TPS) not reading correctly when you're at part throttle.
It is possible to test these sensors with a multimeter for correct voltages etc.
Sometimes an idle control valve (ICV) on its way out makes the car bog down and low throttle and when rolling in gear.
