What to do if your Tach is jumping?
Take off your distributer cap and pull the rotor off, then locate the connecter beside your distributor where the wires connect to the distributor. Disconnect the wires at the connection, using an ohm meter check the resistance of the wires coming out of the distributor, right this number down.
Why is my tach jumping at 5000 rpm?
I put my MSD box and my Auto Meter tach and speedo in and mine kinda does the same thing… when first started the needle jumps about 2000 rpms and then goes away when it warms up a bit. Also, at about 3000 rpm it will jump around 500-1000 rpms.
How does Auto Tune and manual retuning work?
Both are done using your remote control. An auto-tune allows the television set to tune to services from any transmitter that it can receive. A manual re-tune allows you to input and store, one by one, only the correct channel numbers or frequencies for the transmitter your aerial is pointing towards.
Why is my tach jumping on my MSD?
A bad pickup coil will cause erattic tach behavior but will also cause erratic missing, bogging, engine dieing while idling, and other various ignition related problems. An MSD uses the same pickup coil that your stock ignition system uses so the procedure is the same. Ludicrous speed, GO! I had a similar problem with the tach in my 73.

What causes the tachometer needle to bounce while driving?
The bounce of the tachometer needle happens when speed is constant under little to no torque, anywhere between 30-58 km/h, the RPM ranges 1300-1800-ish {if I press or release the accelerator slightly the RPMs stay steady, and the bouncing tach needle stays steady}.
