I also have more knowledge than the average guy off the street. I have training, certification, real-world experience, the ability, will, and desire to read, research, learn, etc. I have done those things and I still disagree with you wholeheartedly. I deal with the public all day, and I haven't murdered anyone yet, so I'd say my skin is thick enough to repel acid, but just thin enough to still feel. My opinions are also based on facts. The claims I make ARE substantiated by mountains of evidence, just like your DENIAL of my claims is substantiated by mountains of evidence. At the end of the day, you just gotta decide which one you believe. No disrespect intended, just letting you know that I'm not new to this world, not new to cars, parts, diagnostics, or forums, and who ever wants to fight me on an issue is welcome to do so, but expect to be called on your inadequacies. So we can do this all day long, but I've got a pretty rewarding life (outside of my unfortunate career choices), so I'm gonna go do something else now.
Oh, to Mr Rchneider, who started this thread - sorry it devolved into something unrelated to your original post. I've been on web forums for different vehicle types or customization worlds for a very long time now, and I can assure you (if you aren't already aware) that this happens all the time. There are people like myself and Ranger and Submariner and Basscatt who all think they're right, either because we pulled facts, perceived facts, or opinions out of our individual posteriors, or because we received a vision from our deity of choice, or whatever. What happens in the end, though, is that your original question gets lost in a tennis match of words being volleyed, ironically, for your benefit.
At the end of the day, you have decide who you think has a good answer. I'll save you the time of trying to figure it out on your own - it's me. But all that aside, I hope you get your trouble straightened out, and thanks for allowing us to have a hoot in your thread!
