Re: high rpm
Sounds like you have joined the club of faulty tach owners. Mine reads 300 rpm high at idle and pegs 7k when it's actually below 6k. There's a fix on the boards somewhere.

Re: high rpm
Do you now have a V-8, in an original six cylinder car? Can you feel the TCC lockup? Have you been lied to before?

Re: high rpm
Is the four wire plug actually plugged into the trans?
Does your engine warm up properly? What thermostat do you have installed?
How many miles on the trans? Fluid full, and pretty and pink?
Do you have another tach (hand held, tach/dwell meter) you can hook up, and see if your tach is accurate?
