    Where is Coil 1 on the 2006 GTO ECT pinout list

    Hi Everyone

    This is probably an incredibly stupid question but where is COIL 1 fed from on the ECU. I've been trying to sort a savage misfire and on close inspection the pinout diagrams I have, I cannot find a Coil 1 control: All the other coils are there

    Am I blind? Or am I missing something simple?

    C2-54 is labeled EVAP Can. Vent. That is incorrect. It's actually IC coil 1. C2-54 is coil 1.
