Idles high when 1st started doesnt accelerate properly

My car has 1220000 miles.
My car has an automatic transmission.

Hi there. Thanks for contacting us today. Usually a high engine idle upon startup, followed by acceleration problems is caused by a vacuum leak or a perhaps damage to the idle control valve. It’s also possible that an error code is stuck in the ECU that is impacting the operation of the engine. The best way to determine what is causing this problem and what repairs should be completed is to have a professional mobile mechanic come to your location to first complete an onsite inspection.
