My 80 k10 the speedometer just kind of wiggle at around 15 mph even I'm driving 60 mph. I realize there a loose cable some where is located on the truck?
The odometer is fully functional that being said yes the miles go up as it should. The odometer is enough to go past 99,000 miles?? I thought the odometer from that era only went to 99,000 miles. Mine reads with a zero first and than 56k miles. I figured I combine the 2 questions I never really had anyone to teach me on these cars and trucks. I'm going to learn from forums and hands on..
