I feel your pain, Phil. I wasn't always a mechanic, and okay, I'm no longer a mechanic, but I remember days and days of diagnosing by replacement, making desperate phone calls or visits in person to anyone and everyone, trying to coax any useful information out of anybody who seemed like they knew even a little bit about the inner workings of a car (or truck, as the case may be).

Some of those people included people whose job it was to fix cars for a living, so by providing me information, it was essentially taking money out of their own pocket...not that I had any money, mind you...but most people were kind, and somehow I survived. It's my way of paying that kindness back. Keep us posted.
