tach fix

Is there anyway to fix a faulty tach? Mine sits a 0 when the car is off, but when I start it, it sits at around 3000 and doesn't move. Or is it time to visit the scrap yard?
 
its not the tach its ur damn IAC valve acting up.. pull the codes and tell us what u get.... even if the CEL is off doesnt mean you dont have any codes... keep us posted...
 
I'm not sure if my question was understood properly. My engine isn't actually idling at 3000 rpm. It idles normally, it's just the tach needle that points at 3000 rpm. Whether I idle or accelerate, it just stays there. Even if I just turn the key to the ON position without actually starting the car, the tach jumps up to 3000 rpm and just hovers there.
