the tach goes crazy and the engine cuts in and out, it will work normal and than stop working and will go crazy swinging wildly thats when the engine will cut in and out. It has a engine speed code. I changed the distributor being told that was the problem but it still does it

 

For a V6, the engine speed output signal for the tach is from the ignition coil.

What specific trouble code number are you getting?

 

Do the gauge needles go down for a split second and then come back on? Does the engine sometimes stall? I have a 4 cylinder 97 accord and there was a recall for the electrical part of the ignition that is faulty, dealership will change it out for free if it has a recall.

 

I'm getting code PO725
Engine Speed Sensor Ckt Malfunction
The car runs fine however when the tach goes crazy it cuts out not for long. It's just feels like a small bucking of the car. I have a scan tool and at a idle the tach was stoping than swinging up and down but the engine speed on the scan tool remained constant it did not fluctuate. I haven't tried it while driving yet.

 

There was a July 2001 Honda Service News article on it many years ago:

Tach Fluctuation and/or A/T
DTC P0725: Accord V6
On ’95-
97 Accord V6s, when you troubleshoot a
fluctuating tachometer or A/T DTC P0725 (lockup
clutch does not engage), keep in mind the
cause could be a faulty resistor in the ignition coil.
The transmission control module (TCM) provides
electrical pulses through this resistor to drive the
tachometer.

Although a faulty resistor doesn’t affect the coil’s
ignition functions, you’ll still need to replace the
ignition coil to fix a fluctuating tachometer or A/T
DTC P0725 - the coil resistor isn’t available
separately. Order P/N 30520-P0G-A02, H/C
4598371, for the ignition coil.

 

Changed the ignition coil and it fixed the problem, tach is working fine and the car doesn't buck anymore . Good call Redbull thanks for the help
