Try another watch approved by NASA
Are you running low low profile tires?
Forget the cable.On second thought,pull off cable at top and apply
several drops of 3m oil.Ok now, IMHO I don't believe it could possible
be the cable.
Got a tac? what does it say.
Look on the bright side , you will pobably never get a speeding ticket
and your engine will last longer. Unless of course your runninf 12"
tires.   Marcus
