Tachometer issues

[pixie]

Hey, my mustang's tach is wonky. It reads about 1000 lower than it should.
Occasionally it will work right, and my check engine light will go off and the car will run fine, but when the check engine light comes back on, the tach goes funky again, and the car runs like crap (won't accelerate well, hesitates).
Anybody got any ideas? I asked a tech at the local dealer about the tach, and he blew it off like it wasn't a big deal....

Any help would be appreciated.

Thanks

They have a 92 so no distributor...Replace the ignition module and all will be well (it's located on the front of the intake manifold...a plug going into the top and bottom of the grey module.

Wonky?
