MPH Needle (Jumps)

What makes the needle jump when in drive? Never see it at idling! Just started noticing it like 2 weeks ago!

the speed-o cable is drying out... can either take it out and put some lube thru the cable or replace it (junk yard)

^^^^yup

listen to those guys. Mine done the same thing now my cable is broken.

if it isnt drying out,which is sounds like it probably is, the cable may not be plugged all the way into the cluster. I've had that case happen on mine when swapping to a tach cluster.

mine only does it til bout 25 mph then its fine

i'll out the cable.....Thank you guys

Mine does this when it's cold out I think it may need lubed up on the cluster I hate plugging the bastard back in though lol. I already had to lube up the blower for the damn heater it was squealing like a stuck pig.
