Well, you can still owe me a beer, but I'll settle for doing a burbon run with you some time.

Pico is just an oscilloscope. But you do mention something that is worth thinking about. Instead of doing a pico scope I could just hook up my voltmeter.

Here is the question I have though. Coil has 3 wires going to it. ground, a voltage (not sure what voltage) and another wire. In coil ones case it is brown, black, green/black. Brown is obviously ground. But should the black wire have? voltage, ground, ?. What should the green/black wire have? The green/black wire is what comes from the dme. Dont know where the black wire really goes other then it's used by a lot of things. Injectors, all the coils, 02 sensors.

Who is our resident wiring diagram expert?

Not discounting this being a wiring issue. 2 common things with this issue for wiring. DME & bank 1 coils all use the same ground point. GP12.
