When my car is off, the tach reads 600. It shows to idle around 1500. Has anyone ever heard of this. I also have white face gauges, but I compared them to my friends 96 and the gauges look the same.
Turn the key on, but don't start the motor. The needles should all zero out. With it like that take the tach needle off and put it back on the correct way.
With a '96 you will have to take the clear face off your pod, pull the tach needle off, hook up a hand held tach. Set a specific RPM, say 2500 or 3000-hold it and set the tach needle to agree. You CAN'T set it with the engine off.
