Ok, here's one that's been bothering me for a while now. the truck is a 2000 GMC Sonoma 2WD, 2.2L engine, automatic trans.
Whenever I go above 65-70 MPH, the speedometer needle will "quiver" back and forth constantly. It moves up and down, varying by 1-2 mph. If I have the cruise control on, it goes nuts and speeds up/slows down with the speedometer. The ABS light will also come on, and the red BRAKE light will flash at random.
Could this be a bad speed sensor? I haven't had it looked at and I'm damn sure not paying the stealership $45 just to "look" at it. I know nothing about these newer plastic, computer controlled vehicles. HELP
Thanks, Tony Kimmell
