I understood most of what you said about calibrating the TP sensor but got
just a little fuzzy on this sentence.
> it should be roughly 0.15v relative to zero if the battery is 1.5v.
Did you mean 0.15 volts? Or was it a typo? If you could explain it again
it
would be very helpful. This is potentially a real money saver for people
with this problem on an out of warranty repair. I understood the rest of
it.
I have used reverse bits to remove studs and shear bolts before and it
works
pretty well if you drill a small diameter pilot hole in the exact center
of
the broken stud or bolt. Have even done very small bolts like the ones
that
hold on the distributor cap. It was a lot cheaper than buying a new
distributor but it requires a steady hand and the patience of Job.
Where did you learn how to do this? I can't believe Honda put it in a
service manual.
