The speedomter on my 90 SC starts to jump when going +110mph. I have tried 3 different speedometers and all of them do the same thing. Has anyone had this problems and what did you do to resolve them ??
Thanks..
:cool:
 
Hi All.
I had my speedometer jumping, and it was the sensor in the transmission.
Thanks Vidar.
P.S. And a Happy New Year to All :cool:
 
Either a bad transmission sensor or the beginnings of a bad cam sensor.
