For the past 10 years, I've been restoring this car. Can proudly say that, even at a low idle, I can balance a nickel on the ignition amplifier. This is a hobby for me, I have made all of the repairs over the years myself.

Problem:
Despite the fact that it idles so wonderfully, I came to the realization only the "A" bank fuel injectors were firing. I have unplugged the wiring harness, and verified connectivity to each of the "B" side fuel injectors. I also unplugged the eight pin connector leading back to the ECU and only had voltage to the "A" side. Does anyone have a computer that I can borrow or buy? Feel free to call Kevin at 404-441-7793.

It idles wonderfully with only one bank running? ??!!!

Have you checked the connections to the pull up resistor pack? The ecu fires the injectors, but the pull up circuitry is what holds the injector pulse for the programmed duration. On my S3 V12, its located in the front right (passenger) part of the engine bay, mounted on the fender behind the radiator
