I never questioned his work. I doesn't matter who you are and how good you are something as small as accidently unplugging something can happen. Hell I was in such a rush to get my car back together at the track I forgot to take the paper towel out of the TB when I had the intake off. We all make mistakes and that one I have never made again. haha I made it to the staging lanes just before I had to run. The car I just put a motor in had it's rad fan relay quit 1 week after the swap, I didn't cause the problem but I still fixed it.
