Well, I was thinking that it'd be another thing to check. But true, many times the ambient temp. sensor failure shows us as a rich mixture when warm.

Thinking on it some more though, have you checked that you have a strong spark on that #1 cylinder? Maybe you could swap the plug and / or wires around to see if the failure follows the components.

Not saying it's not what you suspect. Just trying to cover all the cheap bases.

Edit. I'd have no problem pulling the plug wires while running to isolate which cylinder as you asked above.
