Well, that is the problem isn't it? They have the book and it is behind the desk! But even if it were the proper one I think it is toast anyway, I have pretty well eliminated any of the obvious problems and it has never changed anything. As I was driving home a few months ago and it just shut down on me, backfired and when it came back to life it ran perfectly! Next time, it fired up and went right back to refusing to idle and taking it a few minutes to clear the gas out of it. It is haunted...it has a demon.
I wish it were an older model without all that computer controlled stuff on it but I am sure that if it were working properly I would never give it a second thought!
