I recently found that my 91 was running like a pos.  I replaced the plugs,
did a tune up, replaced the tail pipe that had a small hole in it, replaced
any sensors I thought might be the/a problem.  I ended up finally knocking
out the Catalytic converter after reading up online.  It made all the
difference in the world, at least till now.  Yesterday my 16 y.o. daughter
was driving it to school and noticed it was hot.  Luckily, I was home and
she called me  from 5 minutes out.  I dashed over to find that the water
pump died and was shooting straight out the blow hole thingy(?).  I think
I'll do it myself since the locals want 460 to get r done.  I will also do
the thermostat.  Question is, should I go with the 87 degree one or the
cooler (80 I think) one.
