with my 98 gt and 99gt installed motor my tach hasn't been right since. goes backwards or goes up to normal but still never reads write. just wondered if anyone else has this or ever heard of this problem. thinking of installing MSG coil pack on to see if that helps. i used the coil pack off 98 motor.
? the car runs great but with wacky tach. thanks Dan Heagy VP Mustang Club of Maryland
