Car overheats and check engine

This is a 2 part question--

The car in question is an 88 Acura Legend, 2.7L V6, auto tranny, 172000 miles. When I drive this car for 10 to 15 minutes at both highway speeds and city speeds, the temperature gauge goes off the charts, smokes, and it runs kind of boggy like it is misfiring. I recently (in the last 2 days) replaced the upper and lower radiator hoses, and the thermostat and fluid. The upper hose had a leak in it (I noticed this 3 days ago, thus the replaced hoses).

Today I drove it, and it did the same thing minus the smoking. I am guessing, but this leads me to believe that I have a bad head gasket. Any other suggestions?

Part 2: The check engine light comes on when I am driving at highway speeds for more than 5 minutes, and at city speeds for 20 minutes or so. Is this just a by-product of the above listed problem? Maybe a temperature sensor triggering a warning....? Dunno....

Any light you can shed on this is much appreciated!!

Any answers to this question would be guesses
Have the codes read, that's what they are for
It could be related, or not at all

You possibly have a bad water pump
You now almost certainly have a head gasket problem
The constant overheating has quite possibly warped the heads
