Tach problem....
Since I've had the car I've noticed my tach to rest at 3k rpm's. When I start the motor it jumpes to 4500. Give it a little gas and it redlines. The tach is obviously working, it's just set way to high. What can I do to fix this?

:iagree: Mine did that for a while then the needle fell off ........ new board will fix it. The board replacement is easy ... rippin the tach out of the dash is a true PITA :mad

I think that if you pull the needle off, and put it back on such that it reads 0 when the car is off, everything will be ok. The internal electronics doesn't have any way of knowing which way the needle is stuck on.

Re: Tach problem.... (aharte)
I think I'm gonna try just to set the needle at zero as mentioned. How do I get the needle off? I was looked at it but I couldn't tell how it's fastened.
