Hi there my Tach reads about 5000 rpm at idle, I have checked the wiring as per the factory manual.
All the circuits checkout okay, I have replaced the Tach as recommended by the manual but the new one does the same thing, where do I look next?
have the same problem?

Exchang out your curcuit board as this is usually the problem, I had the same problem and it cured it

I had the same problem with the tach on my 92 Camaro. Tried the resistor fix but it didnt work. Finally found a tach board at the junkyard that worked for about a year.
I found a new replacement tach board. Only had it for about a week but it seemed to fix the problem! Hurray!!
