    I start up my 97 355, let it warm up and all is normal. I drive around and the car comes up to full operating temp, then I come to a stop at an intersection. The car wants to idle at 2000 RPM. The heater is on and working good, I push the environment control button to shut it off and the idle drops immediately to normal range. Is this normal?

    Not normal--wonder if you are seeing a ground<ing> problem developing.
