When Cold the car had a hard time idleing until you warmed it up a little. The heater in the car was having problems too. I changed the Thermostat last night and found the old one was stuck open. After replacing the thermostat, the car idles fast when cold then once warmed up it starts to idle down then up then down and keeps pulsating as such. Then you drive it, it seems ok but when you stop at a stop sign it starts idling up and down again.
