I was wondering what would happen if one were to drive around the neighborhood with the diesel purge bottle set up secured under the hood. I really don't like to rev my engine in neutral. I don't even like to let it idle in park or neutral. I picture things spinning around too fast in there...sort of like a MLB pitcher throwing a ping pong ball. Thoughts?
