Colorado W/T 2.9L

  • Manual transmission

Every singe time i start the truck and let out of the clutch the speedometer jumps to any where from 20 to 110 mph and wont go down unless you start to move or rev the engine and when i have the ebrake on and it does this it sounds like i just one the jackpot it dings so loud and flashes because it thinks im moving with the brake on.
