Tach Has Mind Of Its Own
Does anyone have any input on how to fix a tach from a 82 trans am? When it first starts up, it goes to 4500 at idle, then all of a sudden bounces back to "idle". Upon throttling up, the needle moves, but not in a accurate or precise manor. My car is 305H, no tach filter, the tach has a pretty brown spot on the printed circut board. I have read in here about people replacing some parts on that board, but the tachs that they were repairing were different than mine. I even tried another second hand tach from another 82 TA, it wanders too but in a different way. It will idle at 2500 and slowly move up as i throttle up. Is there anything else on the car to test, or do i just have two tachs that are out of calibration??

Are you running an ignition box (MSD, etc.)?

You're talking about the tach.. tho do you mean the
engine is acting up ?
Does the idle follow what the tach indicates ?
