Yup. I added a bulkhead connector to simplify engine removal and the injector trigger wire for 1-2-3 wasn't secure and pulled out, so no fuel was being injected on 1-2-3. I'm now pulling all the pins out of that connector and making sure they're all 100% secure.

The 914 exhaust is separate plumbing for left bank and right bank. So the O2 sensor I added happened to be on the 'running' side, so it read realistic numbers, meanwhile the DME was on the 'dead' side and was adding extra fuel to compensate for the lean/non-running side.

But it's amazing how smooth a 3.2 will idle and even run with half the engine dead.
