Sounds like the engine is idling to high. There is a procedure that you must go through to set it. Reply and I will let you know how to set it.

If your car is fuel injection,try changing the cold start temp sender.

if the car is stock i would replace your oxygen sensor. you may also need to clean out the MAF sensor.

with autobox 750 to 850 otherwise the engine will cut out

you need to do engine tunning
