Wooo...quoting myself! Ok, so here's what I've done...
Replace plugs
Replace ignition coil
Replace Air Filter
Replace vacuum hoses almost everywhere (could have missed some, I guess)
So, after all that, the car runs better (no more missing at idle), and dies less than before, and now that I've replaced the coil, it will actually start again when it dies (before, it seemed the coil would get warm, and if I was so unfortunate as to let the engine die, I would be stranded for about an hour, presumably while the coil cooled off...at least, that was the working theory) but still, if I'm on the freeway cruising along, and I let off the gas, push in the clutch, it'll drop down to about 1k, and start working it's way lower (sometimes quicker than others, but within a few seconds), and die on me. Or if I'm coming up on a light or stop sign, and have to let off the gas, it may die. This is intermittent...doesn't happen consistently, and I can "save" it usually by tapping the throttle (maybe a couple tries) a bit to keep it from dropping, and it will sort of "catch" and idle just fine.
Finally, sometimes, it will be idling happily for an extended period (like if I'm parked), and will inexplicably start to creep toward 0 RPM until it just dies....other times (like today, in the car wash), it will idle indefinitely without issue.
So, what do you guys think? If I keep replacing parts like this, I'll have a new engine soon, but for right now, I think I'd rather find the problem so I can drive this thing to work! One thing to note, which shouldn't affect this (but what do I know?), but might be relevant...I broke, and have bypassed a BVSV (

Oh, and one last thing (sorry for the longish post)...I'm leaking oil, only at high RPMs, and it *seems* to be coming from under the header...seems to be smoking from underneath. I can rev it by hand, and watch smoke come up through the front of the engine...thought it was the oil filter today, since it seemed to have a bit of oil collected around the bottom (none on top of the filter), but even after tightening it down pretty good, it still did it. I proposed that it smelled more like exhaust than burning oil (maybe the infamous cracked header?), but none of my mechanical-type buddies agreed, saying we'd hear a hissing or something if that were the case. While I do notice some strange whistling on the freeway, I definitely don't hear a hiss when it's just sitting there.
So, that's it guys...I'm interested in your thoughts. If you have any questions about the problem, let me know, and I'll give you as many details as I can! As always, thanks for your brain-minutes!
