Overheating?
 
                I have a 2002 Honda Civic EX 85,000 miles Automatic 1.7L Engine
My engine keeps overheating while I'm driving slow, stopping on stop lights, in traffic, etc. When I start driving again, it starts falling. When I accelerate really fast, for example, to pass a vehicle, the temperature shoots up almost  immediately. When I'm on the highway, everything is fine. I have changed the thermostat  and the antifreeze and coolant is at the level it should be. Any suggestions of what could be the cause for this?
Thank you in advance!
