I bought my 1997 A4 about 6 months ago. It has a few thigs done to it. One of the things is a chip. One day i got a little curious and took the chip out to try and find out what kind it was. Well I for got to un hook the battery and I grounded it. The car still runs fine except that when I rev it up and let it fall it falls below normal idle then rises and falls then ries once more then it is fine. Is the chip ok or do I need a new one? Could it just be rewritten? Or could it be some thing else?

the throttle probably did not align itself. doing this will align the throttle after removing the ecu or battery.
