random speedo issue hey guys i have a 98 z and i got in my car today after work and was letting her warm up. i tapped the throttle a little and i noticed the tach went up and so did the speedo lol. only went between 5 and 10 mph but i figured i would see if anyone has the same issue and if so what can i do to fix that if there is any.

I've seen a few GM vehicles were the speedo moves a little if you rev the engine up and bounce it off the rev limiter, but not from just tapping the throttle. Is your speedo still working and showing the correct speed?
