    Thanks for all the responses to my question earlier. I went to a
    junkyard and got a throttle body to replace the sensor. However, I
    can't get the sensor off the junker throttle body,with either a screw
    extractor or having dremeled a notch in the screw. I'm not sure I can
    get the old one off my current throttle body either without taking the
    throttle body off either. So:

    - can I just replace the whole throttle body? The junk part only
    showed 150K (it was a manual). My car has 263K (auto). This seems like
    it would be a lot easier/faster.

    - if so, can I reuse the current throttle body gasket, or should I get
    a new one? They are available from the dealer.

    I'd get a new gasket.

    did you try the chisel like i said? i guarantee it works. also, whack
    the head of the shear bolt end on a little to loosen the threads. doing
    the t.p.s. on the car is a good deal quicker and easier than taking off
    the throttle body and all the plumbing, gaskets, etc.

    the bolts may be frozen into the aluminum throttle body.
    Does PB Blaster penetrating oil work on that?

    It sounds like he tried to Dremel slots for a screwdriver and
    sheared/rounded off what "head" was left.He may have to cut off the "heads"
    completely and use a ViseGrip to remove the remaining bolts.(after the TPS
    is out of the way)

    ok, but in terms of getting the tps off the old body, none of this
    matters as long as it can be removed intact. the most important job is
    getting the old sensor off the good car. maybe i've been lucky with
    corrosion-free california vehicles, but i've removed 4 sensors from 2pfi
    88-91 civic's using the chisel method with complete success and about 5
    minutes work. refitting is easy using m5 or m6 [can't remember] machine
