This is the second time I am having problems with my butterfly exhaust valve. The first time, it went out, followed by my main dash computer and as a result (not saying the butterfly valve was the problem) I had to change the whole wiring harness and other electrical components. Thank goodness for warranties. I don't know what is going on but it's going in AGAIN! I haven't dropped it, oil maintenance and everything like normal, just had the 6000mi tune-up 4 months ago. Dealer worked on always. All new electrical everything just about. Now this. Any clues on why this darn valve keeps going out? I mean really, second time in 5 months?!?!
