When I start my truck the odometer starts spinning as if I'm driving 200 mph or something, even though my truck is in park. I made a video and showed it to the dodge dealer and they were helpless. My truck is a 93 D350 dually with a 5.9L cummins, 2 wheel drive, automatic trans. I think it MIGHT be the PCM but am asking for help. Thank you.
