It was a simple fix and honestly I discovered this by accident. Occassionally it happens between 1st and 2nd at start up, even after proper warm up. I'd attributted it to the computer start up cycle. The inquisitive side of me wanted to reproduce the effect hence the 3 times at speed. In the previous incidents (start up) it would restart with no other effects or problems and my baby has never given me any problems. I have 16,000 miles on her without any major problems at all. Perhaps I'll bring it to a dealer for a computer scan.
