    true.......I have no idea how the tach ties in at all unless somehow the vehicle PCM actually kills the motor for just a tick........IDK....... does everything shut off when this happens or just the tach dies?

    Yeah. I know when you hve a bad CPS the car does studder for a minute then the tach falls to zero. But on the other hand I have heard of random stalling issues when the FP relay goes out.

    That's why I went with the CPS
