The parts store should have some throttle plate cleaner. Take the hose off and spray it into the opening of the t-body. You can hold it open with your fingers while you clean the gunk away from the area that the plate contacts, so there is no obstruction to movement. When you start it afterwards, it may take a couple tries and it may miss for a couple minutes, but it will smooth out.
