Hard Starting Cold & Lean Stumble 99 OB

For those searching on this problem as I did...

Cold starting was hard; didn't even have to be that cold. Backfiring and poor drivability until warm, then OK.

No check engine light.

Based on previous suggestions, I replaced the coolant temperature sensor. That completely fixed it. Good thing, too, I'm not sure what I would have tried next.

BTW, getting to the thing is a b*tch. I once did it on my '95 impreza and couldn't remember just how. This article was most helpful! Step by step photos.

Those hoses didn't just slip off, however!
