Key off-tach needle reads about 200rpm.
Key on-tach needle points to zero rpm.
Upon start, needle does not move, tho engine sounds about right-smooth and no misfire.
Tach needle will move abruptly up to approx 3K rpm if you punch the accelerator hard, but drops back to zero when accelerator is released.
No codes or illuminated check engine light.
May or may not be related:
OEM radio inoperative, tho clock in radio does work.
Decklid solenoid inoperative--haven't checked to see if there is voltage at the solenoid.
Car starts quickly & easily, runs smoothly, charges @13.5 volts. Brand new battery. I have had the car for only 2 days, so don't know much else about it.
My primary concern is the tach. Is it a flaky tach filter? Where on the 84 Indy is the tach filter?
