I just wanted to mention that I had similar symptoms and looking at my invoice, it
says that it was from a sticking idle valve.  I have investigated as what the idle
valve is, but it doesn't sound like the same thing as the coolant sensor Joel was
speaking of.  And yet, I had the exact same symptoms that Richard had.  Matter of
fact, I thought Richard had been drivin' my car. ;)  .  So what do a think?
