After a battery change in all toyota’s, it’s recommended you do a relearn reprogram of the idle control. Very simple procedure, the motor must be warm, (not hot). Ok with your foot hard on the brake pedal and the emergency brake on. Turn the key to the on position, then off, turn it to the on position, then off. Then turn to on and start the car, put car in drive and just keep to this until it beeps. You’ll hear it changing the revs until it finishes the reprogramming. Takes about 5 mins. Hope this helps
