ok so im having a problem where my speedo wont usually work until my car is warmed up, sometimes it works right away, sometimes it doesn't, sometimes it only reads my speed when I let off the gas then when I accelerate again it goes back down to 0. it usually has this problem until the car warms up. sometimes it works faster than other times, kinda has me scratching my head In confusion. I know my car is computer controlled rather than the older cable driven speedos. can anyone shine some light on this or have any suggestions on what to check?
its a 3.1 Camaro 92
thanks in advance
