There are 2 things that cause the tach to do this, one is the tach itself has a problem or a connection to it, the other is a leaky plug wire, it sends out radio noise, the tach picks it up and the needle spikes up and down, saw it more than once, sold a customer a tach and it was a bad plug wire.

75vette tack stuck at max rpm, both with engine on

Chances are its not the Tach. Look over the wiring to the tach. Its it brittle about to crust off? Is it shorted to ground? Now that would pin it. Check its connections off the coil. Engine side of this item is usually where you'll find the problem. This is nothing new with a vette definately not serious. Remember the tach responds to electrical signal it gets. Before you do the surgery on the gauge itself make sure nothing is shorting this out.

My car starts up but is at a consistant 3000 RPM and flutters out

I had a Renault Espace that did a similar thing when it was cold, The ECU thought that the engine was -40* according to the Renault engineer. There are two sensors located together on our Espace, it ended up being the temperature sensor next to the coolant temperature guage sensor located on the thermostat housing. I hope this is of use to you. Ian

Tach is short for tachometer and is a device that tells you the speed of the engine, generally in RPM X 1000. A typical speed for a 6 cylinder engine is about 600 to 1000 for idle in Park/Neutral, and 500-800 in Drive or Reverse. This was if you have this on your dash, and can get me some numbers, I can better assist you...accordianman
