Does anybody know if you can disconnect the battery, unplug the electronic throttle body and clean the carbon of the plate and reinstall without reprograming with a VADID cart when you reinstall the throttle body back on the car. Most cars this would be an unequivacal yes but I am afraid to mess with the Microsoft of cars(networked - made to keep dealers in business) without asking first. I would have thought with the battery disconected that the car would not "know" it had been removed? This is my wifes car, I have a 1998 Saab 900 SET and I can do whatever I want to it. Thank you for your help.
