speedometer problem for my accord 94
 

Hi all,

I have a Honda Accord 94 w/ automatic transmission. Recently, the
speedometer starts to jump around after continous driving for about 1
hour or so, while within the 1 hour time, it works well. I stop the car
and turn off the engin. If I start again just after stopping, the same
problem continues. But if I wait for 1-2 hours until the car cools
down, speedometer works well again.

I am not sure is it the problem of the VSS or speedometer unit? If it
is the problem of VSS, autozone sells it for almost 100 bucks. But I
searched ebay, it is asked for only ~30 bucks. Is there any difference?

Thanks for your help!
