first off my name is jonathan and I have a black 2000 cabrio. nothing special but fun to drive. Im hopping someone can help me figure this out. sometimes when I get in the car and start it the tack and speedo dont work the tack just flickers real quick at the bottom and the speedo wont do anything. I think I t might have something to do with the throttle body cause sometimes when it does it the check engine light is on and its a unprogramed throttle code. any one got any ideas? any would help. thanks
