:wah: Sometime when I start my car the tach doesn't work at all. This has happened 3 times already. It starts working again within a few mintues. The shortest time was about 3 minutes, the longest was the 2nd time which was about 30. I know that the hub of the needle isn't the problem because it started working while driving and shot upto the correct engine speed.

Could it be a sender or a lose wire? All the other gauges work fine, so it's not a fuse. This happened to anybody else? :wacko:

yeah, it could be, check the wires.

I would also vote for a loose wire / connnection.
