Hi, have you had this problem with the tach not working right? in my case a idle the tachometer is a hair above 0. If I rev the engine to 1000rpm, the needle moves just to the mark above zero and then goes to the 1000rpm mark when the engine is around 1500rpm.

I have seen the circuit diagram over and over and there is nothing wrong, the grounds are ok, everything good, the question is, what could it be then?

Altough the car has worked since I bought it 5 years ago, is just anoying, and if I recall correctly, the needle has worked right about 2 or 3 times. The last time it suddenly worked right was like 4 days ago.

What could it be then?
