6a13tt ecu output to ignition coils

[ftonoob]

Can someone tell me what the minimum allowed voltage on the signal wire from the ecu to to the coil packs? I used my DMM and got 2.5 dcv on my good coil packs and 1 dcv on the coil pack where I'm getting a misfire. I'm thinking of swapping ecu.
On the wiring diagram the coil packs gets signal straight from the ecu and that is the only difference I'm getting between the bad coil and the good ones.

Does the voltage change depending where the 'bad' coil pack is?

[ftonoob]

The voltage was measured from the harness of the coils while idling. That's why I've ruled out the coils. At the ecu itself I see .18-.20 at the misfiring cylinder and .24-25 at the good cylinders.

Have you tried changing the coil packs around and re-measuring the voltages?

If the Misfire changes Cylinder then it maybe the Coil Pack?

Did that problem stays at same cylinder
