Mazda Tribute..CEL
So one of our great Porsche customers bought his son this little Mazda a while back. Lately is has a stumble off idle and a CEL. Code shows a failure of bank 2 primary coil. Only trouble is that this is a v6 COP car, so there are 3 coils on that bank. After some searching we find a break inside the insulation of one of the wires just beyond the ECU connector.
After cutting back the insulation to reveal the break, and removing the pin from the connector we can repair it.

The CEL cleared with first COER.
