Hey my speedometor is going crazy and people say to check my vss sensor where is it on my 91 prelude

 

on top of the tranny, towards the back, underneath the shift cables

 

ok looked in a manual said 91 prelude has a speedometor cable but if i had a cable why would the speedo jump when i revive the car in neutral? so im guessing must have a vss, somebody else said was under the intake manifold but u have to take manifold off to see it. I'm a little confussed.

 

The 91 Prelude does not have a speedo cable. The VSS is just where Jlude90 said it was.
