Pardon this post from a mechanically inept newbie, but my speedometer in my 99 OB has just started going on the fritz intermittently...once in a while it will stay stuck on zero for a while before accurately displaying the correct speed. I've been ignoring it just because my local guy won't fix speedos and I don't feel like going to the dealer with it (plus I figure it's good for one free get-out-of-a-speeding-ticket pass!), but is my car going to start stalling out and stuff with this...or is this another issue entirely? TIA
