Maybe I should mention that on my '85 it was working. When idling, if I unplugged the line to the EGR, I noticed the idle would raise a small amount, barely noticable. Other than that she ran great. On that one I really think it worked. The strangest thing, though, is that when I unplugged it, my 0-60 times went from about 18 seconds up to around 22. I tested this multiple times and found it to be consistant. I started a thread about this but no one could come up with an answer. It was suggested that I must have done something else while I was under there but I assure you, all I did was put a vac cap on that line. I plugged and unplugged it at least five times and did as many runs on the same stretch of road and my 0-60 time was consistantly 3-4 seconds worse. Since it ran faster with it hooked up I left it like it came. Maybe it had something to do with the '85's special emissions stuff.
