Personally, I didn't think it looked so COOL when I recently when an Environmental Control Valve went out on my Volvo. I was afraid that an injector went bad. I was told later when the mechanics replaced it that it was common on a Volvo for those to go out.
Perhaps if there wasn't actually something wrong with it I would have thought it looked COOL. However, having the valve go out in heavy traffic in Atlanta-on my way to a delivery wasn't very appealing to me.
Call me square but I wasn't in the mood for the traffic say nothing about trying to figure out why all of a sudden I looked like a train with black smoke coming out of my stack!!! 8) :sad: :roll:
