My engine is running hot, coolant bubbles over & under the hood is smoking.

(1999 Mercury Villager)
I'm sure its my radiator but before it died it wouldn't shift out. What does this sound like it could be?

Have the cooling system pressure tested for leaks, also a combustion leak test will show if a head/gasket has failed.

Today when I cranked it to take it to the shop, it was smoking immediately so I turned the ignition off and decided to tow it instead. I tried cranking it one more time before we hooked it up and it wasn't smoking at all. I drove it to town and ran a couple of errands before to taking it to the shop and it ran fine the entire time with no smoke & normal temperature. I took it to Autozone to have them put it on their computer and it showed I had a bad sensor and after reading the descriptions of all the different kinds of sensors, I decided it must be the Massflow. Do any of these symptoms sound familiar?

Did this "smoke" come out of the tail pipe? Was this the first start up after sitting overnight? Does it seem to have a misfire (engine skipping) for a little while, after the first start up in the morning?
IF yes to any of the questions, have a combustion leak test performed on your engine's cooling system! Most any REPAIR shop can do this. When done correctly, it is the BEST, ONLY way really, to check for a blown head gasket. The symptoms you have described sure are indicative of that!! Good luck with it, let us know the outcome.

No smoke from the tail pipe. Yes the first start was after sitting. No skipping or misfiring.

Sounds like you got it hot. Let it cool off then start it and check for bubbles at radiator fill. If it blows water out it's real bad. If it bubbles, probably head gaskets or worst case, cracked heads/block. Check dipstick for oil make sure no chocolate milk look, (water in oil).

After it cools down it doesn't bubble over anymore & the oil is normal color
