'98 3.2 TL, in excellent shape with 65K miles...
I've seen speedometers break. I've seen bouncing and/or floating needles,
dry cable noise, but never this. Stopping for gas, then back onto the
freeway, up to about 65 MPH, but the speedo showed 48 MPH. The odometer
appeared to be functioning fine. Finally, I couldn't take it any longer, so
I pulled off. Back up to freeway speed, again only registering 48 MPH.
Huh? It seems to work fine, as long as I don't exceed 48.
(.....but officer, I was only doing 48!)
