97 Accord V6.....problem starts after engine is warm. Tach will bounce
around (very erratic) and then drop to 0. Engine still runs, but will
stumble slightly. Have ran error codes, and scanner reports nothing...not a
single code pops up. After shutoff, tach works fine till the next episode.
Started out infrequently, but is happening more often as time goes by. Heat
related failure of something ?

replace the ignition coil, I had the same problem . IIRC the dealer coils
was around 80.00.
